Heart block occurs when the conduction of electrical impulses from the upper chambers to the lower chambers of the heart is decreased or stopped, leading to a slower heart rate. Potential causes include ischemia, medications, heart attacks, valve issues, and myocarditis. Symptoms are a decreased heart rate and reduced blood flow to organs, and management focuses on increasing the heart rate through atropine, oxygen, treating low blood pressure, and temporary or permanent pacing.

1. HEART BLOCK

2. Heart block also called
atrioventricular block occur
when thr conduction of the
impulse through the AV nodal
area is decreased or stopped.

3. CAUSES
• Myocardial ischemia
• Medications
• Myocardial infarction
• Valvular disorders
• Myocarditis

4. SIGN & SYMPTOMS:--
• Decreased heart rate
• Decrease in perfusion to vital
organs

5. MANAGEMENT:--
• Increasing the heart rate to maintain
cardiac output.
• Injection Atropine bolus.
• Oxygen therapy.
• Treating low blood pressure.
• Transcutaneous pacing or permanent
pacemaker.
