1. Sinus bradycardia originates in the SA node.
2. Due to reduced sympathetic input or excessive vagal tone.
3. Causes: inferior AMI, hypoxia, hypothermia, drugs (beta-blockers, verapamil, flecanide).
4. At moderately slow rates patient may be asymptomatic.
5. At slower rates, patient may become hypotensive & symptomatic.
6. Management: aimed at increasing HR (Atropine).
