2. Premature ventricular contraction - Wikipedia

   en.wikipedia.org/wiki/Premature_ventricular...

   For patients with more than 1,000 PVCs per day, the risk of developing left ventricular systolic dysfunction after 5 years follow-up is low. Frequent PVCs may increase the risk of developing cardiomyopathy, which can greatly impair heart function. A PVC burden greater than 10% is the minimal threshold for development of PVC-induced cardiomyopathy.

   Atrial fibrillation (A-fib). An irregular and often very fast heart rate. Premature ventricular contraction (PVC). When the bottom chambers of your heart beat too early. ... Treatment options for ...

4. Ectopic beat - Wikipedia

   en.wikipedia.org/wiki/Ectopic_beat

   Ectopic beat is a disturbance of the cardiac rhythm frequently related to the electrical conduction system of the heart, in which beats arise from fibers or group of fibers outside the region in the heart muscle ordinarily responsible for impulse formation (i.e., the sinoatrial node).

5. Tachycardia-induced cardiomyopathy - Wikipedia

   [5] [6] However, the options for antiarrhythmic agents are limited because certain agents can be proarrhythmic in the setting of myocardial dysfunction in TIC. [6] Therefore, RF catheter ablation is often a safe and effective choice for treatment VT and PVCs causing TIC.

6. Cardiac Arrhythmia Suppression Trial - Wikipedia

   en.wikipedia.org/wiki/Cardiac_Arrhythmia...

   The second Cardiac Arrhythmia Suppression Trial (CAST II) modified the enrollment criteria to include patients at higher risk for serious arrhythmia. [4] This included 1) patients enrolled within 4 to 90 days of a previous MI, 2) a left ventricular ejection fraction lower than 40%, 3) prior to enrollment, suppression of PVCs had occurred with the drugs (vs. placebo) using a double-blinded ...

7. Artificial cardiac pacemaker - Wikipedia

   en.wikipedia.org/wiki/Artificial_cardiac_pacemaker

   Percussive pacing, also known as transthoracic mechanical pacing, is the use of the closed fist, usually on the left lower edge of the sternum over the right ventricle in the vena cava, striking from a distance of 20 – 30 cm to induce a ventricular beat (the British Journal of Anaesthesia suggests this must be done to raise the ventricular pressure to 10–15 mmHg to induce electrical activity).
