Study Notes

Medication Recognition

Recognize medications (multiple choice questions)
Understand suffixes.

Beta Blockers

Cardio Selective: Blocks only beta-1 receptors in the heart, reducing heart activity.
Non-Cardio Selective: Can block both beta-1 and beta-2 receptors.

Action Potential Phases

Phase 0: Rapid depolarization.
Phase 1: Initial repolarization.
Phase 2: Plateau phase.
Phase 3: Repolarization.
Phase 4: Forward current.

Antiarrhythmic Agents

Adenosine is used for its antiarrhythmic properties in supraventricular tachycardia (SVT).
