Circulation: Arrhythmia and Electrophysiology

Arrhythmia is a heart condition in which the sequence of normal electrical impulses of the heart that coordinate heartbeats get changes. The rhythm might get either too fast called tachycardia or gets too slow card bradycardia. In short, we can describe arrhythmia as irregular heartbeats. It can be prevented by reducing high blood pressure, controlling cholesterol levels, losing excess weight, taking a heart-healthy diet, etc.

The drugs used in arrhythmia include
- Amiodarone
- Flecainide
- lidocaine
For Tachycardia: Beta-blockers- Acebutolol, Atenolol, Metoprolol, etc
For Bradycardia: Theophylline- Aminophylline,
Ventricular fibrillation: Atropine, Isoprenaline, etc

Electrophysiology: It is a branch of neuroscience associated with the studies of the electrical properties of biological cells and tissues. This technique detects the activity of living neuron by investigating the molecular and cellular process that governs their signaling. The test an electrophysiologist performs includes
- Electrocardiograms (ECG or EKG)
- Echocardiograms
- Electrophysiology studies.

Electrophysiology is majorly used for the investigation and treatment of
- certain Arrhythmic conditions like Atrial fibrillation, bradycardia, tachycardia, supraventricular tachycardia,etc
- Sudden cardiac arrest
