Figure 1: ECG Strip
Atrial Fibrillation (AF) is distinguished by disorganized atrial electrical activity and contraction. The mechanisms underlying AF are not entirely understood but it requires an "initiating event" and "substrate for maintenance."
Table 1: ECG Characteristics
- The majority of AF episodes do not cause symptoms; however, some patients experience symptoms such as palpitations, dyspnea, fatigue, dizziness, and angina.
- Atrial fibrillation can increase the risk of stroke and heart failure.
- Calcium-channel blockers or beta-adrenergic blockers can help treat symptomatic patients.
- Three clinical types of AF can be documented: paroxysmal, persistent, or permanent.
