I am 31 years old and have induced atrial tachycardia which quickly becomes Atrial Fibrillation.Getting my heart rate up its fine till 140 bpm and it starts skipping and turns to afib.I am doing exercises for atrial tachycardia ,if i stop doing exercises like running,moving etc. Should I face an ablation? Please tell me

Answer:Exercising alone is not going to cure your Atrial tachycardia - atrial fibrillation. consider getting a consultation with an electrophysiologist and get on a drug therapy or move forwards with ablation

Hai Doc,when i climb the steps and my heart rate rises and beat becomes faster ie; 90 to 102 and am feeling very uneasy at that time.Is it normal for everyone when climbing the steps or else i have to worry about my health.

2015-05-01 Answered By : Dr. Dhanunjaya Lakkireddy,MD, FACC, FHRS

Answer:Looks like you have slightly higher baseline heart rate. A lot of factors go into higher baseline heart rates - being out of shape/ obese/ lung disorders/anemia etc. Without knowing your clinical situation I can\'t make any guesses why you have higher baseline heart rate. Get it checked since you are getting short of breath. See a doctor

hi lakkireddy, I have atrial tachycardia and have been on Flecanaide for about a week.I am having different chest pain and also having breathless, wheezing ,exhaustion after very little exertion.I have pains in my joints,I didn't have headaches before but am getting regular headache and sensitivity at the top of my scull.what i have to do and what is your suggestion to me?

2015-05-01 Answered By : Dr. Dhanunjaya Lakkireddy,MD, FACC, FHRS

Answer:Flecainide is an antiarrhythmic drug that does give the side effects you have described in your question. Looks like you are intolerant to this medicine. You should ask your cardiologist to change you to a different drug or consider an ablation procedure so that you don\'t have to be on drugs for ever with a great compromise in your quality of life. Ablation can be salvation here!!

I am a 64 years old male.I had my ECG reports and results shown that normal sinus rhythm with frequent VPCs.Single run of pre mature atrial tachycardia seen in rhythm strip.eft axis deviation, left bundle branch block and recently i felt problem in breathing what does this acutally mean for ?can you give me the clarification on reports.

2015-05-01 Answered By : Dr. Dhanunjaya Lakkireddy,MD, FACC, FHRS

Answer:Based on what you describe on your EKG you have LBBB with PVCs and PACs. LBBB is a conduction system abnormality. Added to your symptoms of shortness of breath - you need to get this further evaluated. Cardiomyopathy is a common cause of LBBB. Get this further evaluated and make sure you are not dealing with one.

I am 23 year old female, I am normal weight and height, and other than asthma have no other health problems. All anti-hypertensive drugs are causing extreme supine hypertension, which is unbearable.My doctors said that,i need to control my fast heart rate. What could be reason for causing the exteme supine hypertension?

2015-05-01 Answered By : Dr. Dhanunjaya Lakkireddy,MD, FACC, FHRS

Answer:I am a little bit confused about your supine hypertension that is brought on by antihypertensive therapy. the details of your case are incomplete for me to make any recommendations. Please see a cardiologist or an electrophysiologist locally

Dr Lakkireddy, I have had paroxysmal atrial fibrillation for 5 1/2 years now. During that time it has progressed somewhat and I spent the last 14 months on daily dose Propafenone. This healthy and fit but cause other side effects that require discontinuation. At this point I am going to get an ablation. My question is my local EP is a very good doctor not particularly high volume and the success rate he quotes are not stellar. I have been considering going to Bordeaux France have the procedure done there as I hear it is a high-volume center with excellent outcomes. In your opinion, how much of a difference does the operator make in long-term outcomes? Finances not withstanding, there is the question of support afterwords if a touchup is required or complications arise. My main focus however is termination of a fib for as long as possible with as few procedures as necessary. Can you please comment on this.

2015-05-01 Answered By : Dr. Dhanunjaya Lakkireddy,MD, FACC, FHRS

Answer:Looks like you have reached a point where Ablation seems to be the next thing to do. Based on your question I did not get which country you are in. Bordeaux is a great place where a lot of good work gets done. Follow up is critically important. You need a good center where you have easy access to the doc and subsequently if you need a redo. If Bordeaux fits that profile then you should definitely consider that. If not then try to find a good center around you. Please email me at dlakkireddy at with further questions

I am female 65 can you tell me if AF always get worse I have had AF only once just take 1.25 bisoporol and now my doctor has said to stop that I am not on AOG Thank you

2015-05-01 Answered By : Dr. Dhanunjaya Lakkireddy,MD, FACC, FHRS

Answer:AF is a chronic disease. If you developed AF once the likelihood of you developing AF again is high. Watch for symptoms and get checked periodically. the simplest thing you can do is to check your pulse and make sure it is not rapid or irregular. Your risk factor profile needs to be appropriately addressed - BP control/diabetes/ sleep apnea/ weight/ alcohol intake etc needs to be taken care of.

My 64 yr. old husband with 13 yr. hx. of asymptomatic AF suddenly developed increasingly serious SOB and DOE, following his HTN meds changed 02/15- amlodipine 10 mg qd stopped, leaving betaxocol 10 mg qd and losartan 100 mg qd and BP increased from 114/65, p-61 to 120/74, p-71. He never had any respiratory problems prior to this routine visit of 02/15 to his cardiologist His Echocardiogram of 02/15 was unchanged. But yesterday to hospital and repeat Echo supposedly showed CHF. Could amlodipine perhaps been preventing the onset of respiratory sx by some mechanism

2015-05-01 Answered By : Dr. Dhanunjaya Lakkireddy,MD, FACC, FHRS

Answer:Amlodipine doesn\'t have any direct effect of congestive heart failure. It decreases BP and positively affect HTN which in turn can help patients with CHF. His new onset HF needs to be evaluated. Rule out CAD or intermittent episodes of silent AF that is rapid which could cause tachycardia induced cardiomyopathy. I am sure his cardiologist is working him through for these issues. You can discuss about the work up with him during his next visit. Make sure he is appropriately anticoagulated since he is asymptomatic his overall AF burden could be underestimated and perhaps under treated.

Dr Lakkireddy, I understand that many patient have the LAA as the origin of their arrhythmia. There are surgeries and devices to effectively remove the LAA. But it serves various functions. Why not ablate around its entrance as you do around the pulmonary veins, preserving its capacity to maintain compliance and produce peptide? This would serve the aging active athlete better than elimination, yes?

2015-04-18 Answered By : Dr. Dhanunjaya Lakkireddy,MD, FACC, FHRS

Answer:In paroxysmal AF patients LAA seems to play a much bigger role in arrhythmogenesis. Ablating around the LAA from inside seems to be appealing - there are technical and anatomic difficulties in getting the job done. Complete electrical isolation of the LAA is very difficult and oftentimes they reconnect much faster. When it is isolated it looses its contractile function - despite rhythm control there will be significant stasis of blood resulting in the clots and higher risk of stroke. often times the area around the LAA osmium is paper thin and has pits that can lead to perforation and major complications. So removing it either by ligating or clipping it eliminates the arrhythmia source also reduces the effective LA volume and we believe also results in the alteration of the sympathetic systems to result in better AFib control. In most of the people the other parts of the heart and body compensate for the acute loss of atrial natriuretic peptide. So that is not something we should worry about.

At 25 years old I had a stim pace Icar catheter pulm ablation 11 months ago. It was done by the best Dr. in NYC. I dont know exactly what kind it was but my AFib was vagal induced from choking, vomiting, or drinking alcohol. I have been AFib free for 11 months until this weekend with some social drinking. My heart rate was approx 130 (pre surg it would be as high as 180). I was in it for no more then 1/2 hr. I took a few baby aspirins as a precaution and I went for a brief jog down the street. I have got buzzed on alcohol several times before with absolutley no issues. Why now? Can it be a freak thing or too much alcohol at once??? What do you think? I am a very responsible person and my concerns will be that I will be leaving the country and I dont need it to happen again. I have no insurance. Thanks for your input.

2015-04-18 Answered By : Dr. Dhanunjaya Lakkireddy,MD, FACC, FHRS

Answer:Alcohol is frequent trigger for AFib. It alters the physiology of the heart muscle and is notoriously associated with occurrence of AFib. My advice to you is to stop drinking Alcohol and get yourselves periodically checked. Read this article for more information on the link between alcohol use and AFib
