#ثريد اليوم عن Bradycardia للمهتمين في المجال الصحي ? https://t.co/a1NGDrufgj

Bradycardia is a condition typically defined wherein an individual has a resting heart rate of under 60 beats per minute (BPM) in adults, although some studies use a heart rate of less than 50 BPM.

Bradycardia typically does not cause symptoms until the rate drops below 50 BPM

Types of bradycardia:

1- Sinus bradycardia is a type of slow heartbeat that originates from the sinus node of your heart. Your sinus node is often referred to as your heart’s pacemaker. It generates the organized electrical impulses that cause your heart to beat. https://t.co/IR3yjbxhy4

Note ? Sinus bradycardia is normal in athletes and during sleep.

In acute MI, it may be protective and beneficial or the slow rate may compromise cardiac output. Certain medications, such as beta blockers, may also cause sinus bradycardia. https://t.co/0ah2Aunjm9

2- Sick sinus syndrome occurs when the sinus node (the heart's own pacemaker) fails and does not reliably trigger heartbeats. This is very common in elderly persons, but may occur at any age. https://t.co/vWIebgckHq
