Cardiac rhythms under physiological conditions are set by pacemakers cells that are normally capable of developing spontaneous depolarization and are responsible for generating the cardiac rhythm.
Cardiac rhythm that deviates from the normal automatic rhythm is referred to as cardiac arrhythmia, often manifested in the form of tachycardia. Cardiac arrhythmia is one of the leading causes of death in many countries worldwide. What is cardiac arrhythmia? Cardiac arrhythmia is a term used to refer to any condition that disrupts the normal electrical activity of the heart which can lead to sudden cardiac death.
Arrhythmias can affect the heart rate causing irregular rhythms, such as slow or fats heartbeat.
In United States, fatalities due to cardiac arrhythmia mostly caused by cardiopulmonary failure, trauma, metabolic imbalance such as renal failure or diabetes or a systemic illness.
Some arrhythmias clearly produce serious hemodynamic compromise that can be fatal, but some cause no clinically evident problems. Other arrhythmias may portend increased risk for sudden arrhythmia detach.
