[Music] cardiac arhythmia can be classified by site of origin sinus rhythms originate from the sinoatrial node or SA node atrial rhythms originate from the Atria ventricular rhythms originate from the ...

There are several cardiac pacing options available to patients with sinus-node disease (SND), but each is associated with clinical disadvantages and the optimum strategy has not been identified. The ...

MANY common arrhythmias observed in both atria and ventricles are similar although the atrial types have a few important distinguishing features. Thus, so far as therapy is concerned, the atrial ...

AMSTERDAM -- Reducing atrial pacing didn't help prevent atrial fibrillation (Afib, or AF) in patients with sinus node dysfunction but did increase risk of fainting, the DANPACE II trial showed. The ...

When high doses of AV blocking drugs are not successful to lower ventricular rates in the setting of atrial fibrillation, AV node ablation can be utilized. Remember that all atrial action potentials ...

The heart is a muscular organ composed of four chambers: two upper chambers called atria and two lower chambers called ventricles. These four chambers pump blood through the body in a rhythmic pattern ...

Disruption of the Sp1-related transcription factor HF-1b leads to alterations in the cardiac conduction system that result in ventricular arrhythmias and sudden death. What does this tell us about how ...

Atrial fibrillation and ventricular fibrillation are both types of irregular heartbeats (arrhythmias). Atrial fibrillation (AFib) affects the two upper chambers of your heart. Ventricular fibrillation ...

Atrial fibrillation with rapid ventricular response is a fancy name for an irregular heartbeat. When your heart's electrical signals aren't working right, it can lead to a heartbeat that's too fast.

Medically reviewed by Rafle Fernandez, MD Key Takeaways Ventricular tachycardia is when the lower chamber of the heart beats ...

In Atrial Arrhythmias the cause of the arrhythmia is in the upper chambers of the two atria. Supraventricular Tachycardia (SVT) is rapid heartbeats originating anywhere above the ventricles. It ...

Atrial fibrillation (AFib) with rapid ventricular response is a heart rhythm disturbance that puts you at higher risk for stroke and other serious complications. There are treatment options. Share on ...
