Treating Abnormal Heart Rhythms & Fast Heartbeats

Electrophysiologists, or EP doctor for short, are cardiologists who have additional education and training in the diagnosis and treatment of abnormal heart rhythms. Cardiac EPs could also be considered “heart electricians.” Cardiac health is an important factor, especially as we get older. Every lifestyle choice we make, at any age, plays a role in our overall cardiac condition. At Heart Rhythm Consultants, it is our goal to help our patients manage their condition, whether they suffer from arrhythmias or other irregularities with the heartbeat.

Dr. Dilip J. Mathew, Dr. Antonio Moretta, and Dr. Rajesh Malik are electrophysiologists serving residents of Sarasota, Venice, Tampa, Port Charlotte and Sun City Center, giving every patient the care and attention they deserve.

Dr. Dilip Mathew, Cardiac Electrophysiologist

Dilip J. Mathew, MD, FACC, FHRS, is Board Certified in Cardiology & Cardiac Electrophysiology and has been practicing in the Sarasota & Tampa Bay area since 2004. Dr. Mathew is involved in all aspects of managing heart rhythm disorders such as cardiac arrhythmias. Respectively, he received training in cardiology at Brigham and Women’s Hospital at Harvard in Boston and in cardiac electrophysiology at Lahey Clinic, Massachusetts.

Antonio Moretta, MD, FHRS

Antonio Moretta, MD, FHRS is Board Certified in Internal Medicine, Cardiology, Clinical Cardiac Electrophysiology, and Echocardiography. Dr. Moretta joined Heart Rhythm Consultants, P.A. in November 2018 after servicing the Huntington area for five years. Respectively, he received training in cardiology at Lenox Hill Hospital and Northshore University and in clinical cardiac electrophysiology at Stony Brook University.

Rajesh Malik, MD FACC, FHRS

Rajesh Malik, MD FACC, FHRS is Board Certified in Internal Medicine, Cardiovascular Disease, and Cardiac Electrophysiology. Dr. Malik joined Heart Rhythm Consultants, P.A. in February 2020 after servicing the Bradenton area. Respectively, he received training in cardiology and cardiac electrophysiology at the Medical College of Virginia.

EP Studies & Ablation Procedures

Abnormal rhythms can range anything from very slow heart rates to very fast heart rates. Types of heart rhythm disorders could include bradycardia, tachycardia, premature heartbeats and atrial fibrillation.

Dr. Mathew performs implantation of pacemakers, defibrillators, as well as electrophysiology (EP) studies and ablations. He has a special interest in lead extraction and ablation therapies for atrial fibrillation.

Dr. Mathew has successfully performed over 5,000 of these complex ablations (one of the highest volume operators in the southeastern United States). Dr. Mathew also performed the first left atrial appendage closure procedure using the lariat device in West Florida. Dr. Mathew performs the WATCHMAN procedure and is the only physician in SW Florida to utilize ICE intracardiac ultrasound eliminating the risk of general anesthesia. He is also the first physician in SW Florida to utilize left bundle branch pacing during pacemaker implant ensuring better clinical outcomes to tradition pacemaker placement.

Dr. Antonio Moretta performs implantation of pacemakers, defibrillators, as well as EP studies and ablations. He has a special interest in HIS bundle pacemakers and defibrillators. This is a new and innovative system where Dr. Moretta recircuits the patient’s natural electrical system instead of pacing abnormal heart muscle avoiding certain types of heart failure that is caused by the typical pacemaker.

Using cutting-edge imaging techniques such as intracardiac ultrasound, Dr. Moretta also performs his EP studies and ablations with no fluoroscopy. This means that the procedure is performed without any radiation. Medical testing is the number one source of radiation to patients and radiation exposure is cumulative, meaning that the more you are exposed, the higher the risk of ill-effects (such as certain types of cancer) no matter how long ago your last exposure may have been.

Dr. Malik is an expert in the treatment of atrial fibrillation utilizing cryoablation a proven treatment in addition to radiofrequency to treat afib Additionally dr malik performs device lead extraction procedure for patients whose device leads have malfunctioned and has extensive research experience with radiofrequency ablation technologies.

What Our Patients Have to Say

Before [my wife and I] went to Dr. Mathew, I was struggling to deal with the medications prescribed to control my Afib. I literally couldn’t think straight on one of the medications. I just couldn’t live like that. We cannot thank Dr. Mathew enough for helping us live without fear again. He really took the time to understand how we felt through the whole process. We couldn’t ask for better patient care or outcomes.

My battle with Afib had drained my energy to the point of not being able to spend time with family and friends. [But] Dr. Mathew gave me my life back. Having such a wonderful physician and a life-changing procedure within a short drive, or maybe even walking distance for some folks, is such a blessing for our town.
I am writing once again to say thank you! I truly am so very grateful to you! I feel great and continue to tell people about the quality of your work and your dedication. May you be blessed with good health, happiness, and continued success.

My regular cardiologist suggested an alternative treatment called catheter ablation. He referred me to Dr. Mathew. I underwent this surgical option on May 30 and was released from the hospital the next day and was feeling back to normal within 10 days. Now, less than one month later, I’m back to myself at work and recently cleared to go back to exercising at the gym.


Dr. Malik, I am one of your very, very grateful patients! Last February, you did an Ablachan surgery on me at Venice Hospital. I was in real bad shape and had been in the CTU twice with a heart rate of almost 200. And then…there was you! I remember going into surgery that day…you leaned down outside the operating room, smiled, and said “Don’t worry, I’m going to take good care of you,” and you did. Thank you again from the bottom of my…now fixed…heart!


Dear Dr. Malik,

A note of thanks for all of your care, concern and medical expertise that you have given to my wife, Carol. You make her feel comfortable with your sense of humor, you explain procedure very well, are concise and articulate and finally, you are highly skilled in your profession. Thank you!
