The heart beats throughout life and is essential to maintain life. This beating is the contraction and relaxation of the heart muscle which allows it to pump blood. The heartbeat as it is known needs to be adequate for the body’s needs. This normal heart rate varies among individuals but...
Atrial fibrillation (Afib) is an abnormal heart rhythm caused by erratic electrical signals in the heart. Atrial fibrillation is a progressive disease that worsens.

Those who developed a fast heart rate caused by rapid contracting of the heart's lower chambers—ventricular tachyarrhythmia—faced a twofold increase of dying earlier compared with those who did not have an irregular heartbeat. Patients who had experienced abnormal heart rhythms (atrial arrythmia, ...
Patients with PSVT experience sudden and recurrent rapid heart rhythms triggered by abnormal electrical activity in the upper chambers of the heart. Though the episodes are not commonly life-threatening, they can be frightening and cause shortness of breath,chest pain, dizziness, or fainting and le...
cells and the subsequent rapid "reboot" during treatment causes mitochondria to falter and trigger a whirlwind of aberrant electrical signals. These chaotic signals quickly ripple throughout the entire heart, wreaking havoc in the cell-to-cell electrical signaling needed to keep the heart beating ...
