Question

Excess of this medication is a common cause of junctional dysrhythmias

Answer 1

Excess of certain medications can lead to junctional dysrhythmias, disrupting the normal pattern of impulse conduction and contraction of the heart. Chronic excessive use of these medications may result in fibrillation, which is an uncoordinated beating of the heart.

Step-by-step explanation:

Excess of medication can cause junctional dysrhythmias. An ectopic focus or ectopic pacemaker in the heart can be stimulated by certain drugs such as caffeine, digitalis, or acetylcholine.

These medications can disrupt the normal pattern of impulse conduction and contraction of the heart, leading to arrhythmias. Chronic excessive use of these medications may result in a more serious condition called fibrillation, which is an uncoordinated beating of the heart.
