Holter Monitor
At POTS.net, we provide Holter Monitoring services to accurately evaluate abnormal heart rhythms. This non-invasive cardiac test, performed with advanced monitoring equipment and overseen by qualified doctors, ensures precise diagnoses and guides effective treatment.
Understanding Holter Monitor
Holter Monitoring uses an ambulatory device that records your heart’s electrical activity continuously for 24 to 48 hours. Unlike routine electrocardiogram (ECG) tests—which involve attaching electrodes to your chest and limbs for only a few minutes—Holter Monitoring provides extended observation. This continuous tracking makes it more sensitive and capable of detecting irregularities that may not appear during a standard ECG.
Why is Holter Monitoring Done?
- Detect Irregular Heartbeats (Arrhythmias): Identify arrhythmias that may not be detected during a standard ECG.
- Detect Irregular Heartbeats (Arrhythmias): Identify arrhythmias that may not be detected during a standard ECG.
- Evaluate Symptoms: Monitor symptoms that may be related to heart rhythm disorders, including palpitations, dizziness, chest discomfort, and fainting.
- Monitor Heart Health: Use it to determine the efficiency of treatment for arrhythmias or the state of the heart after a heart attack.
- Assess Pacemaker Function: Assess the effectiveness of a pacemaker in patients with these devices. Holter monitoring is a test that records the patient's heart rhythm continuously for 24 hours.
What to Expect During Holter Monitoring?
- Preparation: Our medical team will explain the procedure and securely attach the Holter monitor to your chest using adhesive electrodes. You can continue your daily activities but will be advised to keep the device dry, avoiding bathing, swimming, or activities that might wet the monitor. Wear loose, comfortable clothing to accommodate the device.
- Wearing the Monitor: You will wear the Holter monitor for 24 to 48 hours, as recommended by your doctor. The device will continuously record your heart’s electrical activity throughout this period.
- Recording Symptoms: You may be asked to keep a diary of any symptoms you experience—such as palpitations, dizziness, or chest pain—and note the time they occur. This information helps correlate symptoms with the data captured by the monitor.
- After Monitoring: At the end of the monitoring period, you will return the device to the clinic. Our specialists will analyze the recorded data and discuss the results with you.
Risks
Holter monitor is safe and non-invasive with minimal risks. Some patients may experience minor discomfort or skin irritation from the adhesive electrodes; however, these symptoms are temporary and usually resolve quickly after the electrodes are removed.

Posted on Google Meghan WilliamsApril 9, 2025Trustindex verifies that the original source of the review is Google. Highly recommend!!! Not only was I able to get all of my testing done in one place, but I’ve also been able to get amazing referrals to outside specialists. This facility is thorough, reliable, and I didn’t feel like just a number. Each person took their time explaining each test, making sure I was comfortable, and felt seen, and heard!!! I’m also a private pay patient and was able to get so much testing done at a discounted rate! Not only do I have answers, but I’m now on a journey to feeling better! Thank you Dr. Suleman and each and every single one of his staff members!! Every single of one of you are absolutely exceptional!!! I appreciate each of you for helping me get my diagnosis’, and not just dismissing me like I have been for years!!Posted on Google ashley montgomeryApril 9, 2025Trustindex verifies that the original source of the review is Google. Dr. Suleman and his crew at THBC have been a great help. I got very sick about 3 years ago and saw doctor after doctor only to be told I was "fine" and its "anxiety" and all my labs are "normal". I had suspected POTS for about a year but couldn't find a doctor who understands POTS or any dysautonomia/autoimmune anything. I finally found Dr. Suleman and he listened, then he gave me options, explained his reasons for each test he offered, then we started the testing, and not only have I got a POTS diagnosis and help from him on managing it in my every day life, I have also found out other issues that affect my POTS along the way. He does so many tests in office, and when I get results that suggest other things, I get my referrals to other doctors who specify in that issue, but are also familiar with Dr. Suleman and also POTS knowledgeable, cause we all know how POTS ties into EVERYTHING! He's worth the wait list to get in, and he's worth the long office visits and many tests because he gets you answers! Anyways, just wanted to say thank you to Dr. Suleman. Thank you for finding out what's wrong, and giving me answers and options to help me live a better life with this new diagnosis!Posted on Google Adoga HightowerJanuary 21, 2025Trustindex verifies that the original source of the review is Google. I’ve been a patient of Dr. Suleiman’s since 2014. He is incredibly busy. A sign says please be patient. When it is your turn he will spend the time he needs to be thorough. POTS is such a complicated disease, it takes time to get a complete history from a patient, then select treatments. Very few cardiologists have the testing capacity his office has.He can do most tests in one place which is uncommon with other doctors who have to arrange all the testing required.He has gone out on limb for me several times. I was a pediatric nurse practitioner.I saw patients.I know how some patients have more concerns than others. Some are way sicker than othersAgain, this disease can cause many symptoms and it takes time to figure it out. Plus the associated illnesses with POTS may be hidden, and he finds them. He found all of it. Very generous. Does not smile often, but he is sincere. If I went to another cardiologist, very few know POTS, EDS, and MCAS, and they’d probably send me all over the place taking days, weeks of time. Dr.S can do it in 5 days. Sure, he isn’t the as outgoing as other doctors, but he knows his stuff. Very, very few doctors know POTS as well as he does. I know we want a diagnosis immediately, we want it taken care of, but it is a long term disease and requires time. I don’t know of such a comprehensive program in one place. Most hospitals do not know how to do a correct tilt table test for POTS.Posted on Google Kamie PorroDecember 13, 2024Trustindex verifies that the original source of the review is Google. Dr. Suleman is amazing! He truly cares about his patients, is a POTS expert (one of the first and for many years the only POTS provider in the area), keeps up with all the latest research and is very thorough. Dr. Suleman has a very academic mind and at times this may come across as stern or impatient, but that is not his heart. Also remember, when we have POTS exacerbations, our brains tend to be a little foggy. Dr. Suleman will do everything he can to help his patients live their best life!! His staff is young but has always been friendly and helpful towards me. I have had no trouble getting my test results printed out to have a copy for myself and for my PCP. I've been coming to the Heartbeat Clinic for over a year and they gave me my life back!! I read these negative reviews and believe these come from patients being overwhelmed. Not every personality will click, but rarely will you find a doctor who wants to treat everyone with this debilitating condition because he truly cares and wants to help. He is older and if he got sick, think how many patients would not receive treatment. That is why he takes many precautions during appointments. I am very grateful for Dr. Amer Suleman.Posted on Google Zach GNovember 25, 2024Trustindex verifies that the original source of the review is Google. Dr Superman can and will change your life with his excellence in diagnosing and treatment.Posted on Google Amanda FavorsOctober 30, 2024Trustindex verifies that the original source of the review is Google. This is one DR that I can say actually cares about his patients. His staff are always friendly and caring also. I recommend him to anyone that needs a cardiologist. I see him for POTS/syncope. By the way if you are ever in his office look around and see all his research.Google rating score: 3.7 of 5, based on 45 reviews
