Heart Rhythm disorders are a condition that affects the normal heart rate. The heartbeat may be too slow medically termed ‘bradycardia’, too fast or ‘tachycardia’, or irregular rhythm of heartbeat. These conditions affect the amount of blood pumped by the heart.

Structural changes in heart tissues, insufficient blood flow to heart tissues, stress conditions and/or delayed or blocked electrical signal from heart muscles controlling the heartbeat can cause these disorders.

The Sinoatrial (SA) node, also termed as natural pacemaker of heart regulates the electrical impulses that make the heart chambers to contract in a specific order. Malfunctioning of cells producing electrical signals and/or of the pacemaker result in delayed or blocked impulses leading to an irregular heartbeat. Heart rhythm disorders can damage heart, brain and other vital organs of body due to the insufficient blood supply.
