In medical terms, PMT stands for Pacemaker-Mediated Tachycardia. This condition occurs when a pacemaker, a device implanted in the chest to regulate the heart rhythm, inadvertently causes a rapid heartbeat. The pacemaker, instead of correcting irregular heartbeats, might contribute to a fast heart rate.
PMT is a relatively uncommon but potentially serious issue. It can cause various symptoms, including dizziness, shortness of breath, chest pain, and fainting.
