<h3>What is Cardiology?</h3>
Cardiology is a field of medicine that deals with problems with the heart and cardiovascular system.
The term "cardiology" comes from the Ancient Greek words "kardi" (heart) and "-logia" (study).
Heart failure, valvular heart disease, congenital heart defects, coronary artery disease, and electrophysiology are all covered in the field's spectrum of medical diagnosis and treatment.
Cardiologists are among the professionals in internal medicine who work in this area.
Pediatricians that specialize in cardiology are known as pediatric cardiologists.
<h3>Why does cardiac happen?</h3>
Nearly all heart conditions that are known to exist can result in cardiac arrest.
The electrical system of a damaged heart malfunctions most frequently during cardiac arrests.
An aberrant heart rhythm like ventricular tachycardia or ventricular fibrillation is brought on by this defect.
