WebRight axis deviation. The electrical axis of the heart is the net direction in which the wave of depolarization travels. It is measured using an electrocardiogram (ECG). Normally, this begins at the sinoatrial node (SA node); from here the wave of depolarisation travels down to the apex of the heart. The hexaxial reference system can be used to ... WebAn atrioventricular block (AV block), also known as a heart block, occurs when an atrial impulse gets delayed or completely blocked at some point along the electrical conduction system of the heart. There are three degrees of AV block, according to the location and severity of the nodal block.

WebArrhythmia Study Guide – 4 – Blocks, Pacers, and Weird Stuff HEART BLOCKS The AV junction is the area that provides the electrical link between the atria and the ventricles. An abnormal delay or interruption in the impulse conduction is an atrioventricular block (AV Block). The PR interval determines the type of block. WebNon-DHP calcium channel blockers include the drugs diltiazem and verapamil. These drugs are myocardium selective, meaning they act specifically to block calcium channels in the heart. Clinically, these drugs are used to treat supraventricular tachycardias like atrial fibrillation. Common side effects include bradycardia, heart block, and constipation. four wheeler tyres
