Add to cartWhat is an arrhythmia?
An arrhythmia is an irregular heartbeat rhythm that can be too fast, too slow, or erratic, disrupting the normal sequence of electrical impulses in the heart.
input text value
What is the primary tool used to diagnose arrhythmias?
The primary tool used to diagnose arrhythmias is an electrocardiogram (ECG or EKG), which records the electrical activity of the heart.
input text value
What is sinus bradycardia?
Sinus bradycardia is a type of arrhythmia characterized by a slower than normal heart rate, typically below 60 beats per minute, originating from the sinus node.
input text value
What is sinus tachycardia?
Sinus tachycardia is a type of arrhythmia where the heart rate is faster than normal, typically above 100 beats per minute, originating from the sinus node.
input text value
What are premature ventricular contractions (PVCs)?
PVCs are early heartbeats originating in the ventricles, causing a feeling of skipped or extra beats and potentially leading to more serious arrhythmias if frequent.
input text value
What is atrial fibrillation?
Atrial fibrillation is an arrhythmia characterized by rapid and irregular beating of the atria, which can lead to poor blood flow and increase the risk of stroke.
input text value
What is ventricular tachycardia?
Ventricular tachycardia is a fast heart rhythm originating from the ventricles, often requiring immediate medical attention due to the risk of progressing to ventricular fibrillation.
input text value
What is the normal range for the PR interval on an ECG?
The normal range for the PR interval on an ECG is 0.12 to 0.20 seconds.
