List of av nodal blockers
WebDrugs that slow the conduction of the electrical signal through AV node, such as beta-blockers, digoxin, calcium channel blockers, and amiodarone, can cause heart block if … WebThe SA node is often referred to as a natural pacemaker because it generates a series of electrical pulses at regular intervals. The pulse is then sent to a group of cells known as the atrioventricular node (AV node). The AV node relays the pulse to the 2 lower chambers of the heart (the ventricles).
