The heart monitor is a 24-hour electrocardiogram. The leaves are hooked up from your chest to a small machine about the size of an iPhone that you wear on your belt or at your waist for a day, and then you would return to the office. This machine is unplugged and then we process it to determine the total number of heart beats, The average number of heart beats, The slowest it went, The fastest it went, Whether there were extra beats, Whether there were too few beats, Does the person need a pacemaker, do their medicines need to be adjusted, etc. Dr. Barry recommends this heart monitor to be done every year on people with a condition called atrial fibrillation in order to make sure they are properly treated with the medicines but it is for many people who have fainting spells or near-fainting spells, or dizziness, or feel palpitations or irregular heartbeats, this is a very straightforward easy test to give us an idea if there’s a real major problem or not.
