Cardiac Arrhythmias and Their Management Quiz

Cardiac arrhythmias may cause chest pain due to inadequate blood flow to the heart.

ICD's primary purpose is to restore normal heart rhythm by delivering an electrical shock in case of irregularities.

Atrial fibrillation is characterized by an irregular heartbeat, increasing the risk of blood clots and stroke.

Supraventricular tachycardia is characterized by a fast, regular heart rate originating from the atria.

Paroxysmal supraventricular tachycardia is a brief episode of rapid, irregular heartbeats that often resolves spontaneously.

The electrical impulses in the heart travel from the SA node through the AV node, Bundle of His, and Purkinje fibers, coordinating the heartbeat.

Lidocaine primarily blocks sodium channels, making it effective in treating ventricular arrhythmias.

Hyperkalemia, an elevated potassium level, is commonly associated with the development of arrhythmias.

Fibrillation is the term for an irregular and chaotic heart rhythm, commonly observed in atrial fibrillation.

The P wave represents atrial depolarization in an ECG, indicating the initiation of the heart's contraction.

Tachycardia is the term for a heart rhythm exceeding 100 beats per minute.

Pacemaker implantation involves placing a device in the chest to regulate and normalize the heart's rhythm.

Class III antiarrhythmic drugs primarily work by blocking potassium channels, affecting the repolarization phase of the cardiac action potential.

Asystole is the term for a temporary cessation of cardiac activity, often observed during cardiac arrest.

Supraventricular arrhythmia is an abnormal heart rhythm originating above the ventricles.
