Answer 1

Ans. 14.The patients rhythm is sinus bradycardia.

Sinus bradycardia: frequent in normal individuals during sleep and those with high vagal tone, as athletes and young healthy adult. Several drugs (digoxin, beta blockers, clonidine, opioids, sedatives, hypnotics, amiodarone) may induse sinus bradycardia.the most common pathological cause of sinus bradycardia is acute myocardial infarction followed.

Features:heart rate below 60 beats per minute.A p wave preceding the qrs complex, with a normal axis of the p wave.

PR interval between 0.12-0.20s.

QRS less than 0.12s.
