Overview
An ECG may be helpful in the diagnosis of Sudden cardiac death. Findings on ECG associated with sudden cardiac arrest include Sinus tachycardia (39%), abnormal T-wave inversions (30%), prolonged QT interval (26%), left/right atrial abnormality (22%), left ventricular hypertrophy (17%), abnormal frontal QRS axis (17%), delayed QRS-transition zone in precordial leads (13%), pathological Q waves (13%), intraventricular conduction delays (9%), multiple premature ventricular contractions (9%), normal ECG (9%).
Electrocardiogram
An ECG may be helpful in the diagnosis of Sudden cardiac death. Findings on ECG associated with sudden cardiac arrest may include:[1]
- Sinus tachycardia (39%)
- Abnormal T-wave inversions (30%)
- Prolonged QT interval (26%)
- Left/right atrial abnormality (22%)
- LVH (17%)
- Abnormal frontal QRS axis (17%)
- Delayed QRS-transition zone in precordial leads (13%)
- Pathological Q waves (13%)
- intraventricular conduction delays (9%)
- Multiple premature ventricular contractions (9%)
- Normal ECG (9%)
==2017AHA/ACC/HRS Guideline for management of sudden cardiac arrest and ventricular arrhythmia==[2]
| Class I (Level of Evidence: B) |
|
| Class of recommendation | Level of evidence | Recommendation for ECG and exercise tredmile test |
|---|---|---|
| 1 | B | In patients with wide complex tachycardia and hemodynamically stable, 12 leads ECG should be obtained |
| 1 | B | Exercise stress test should be obtained in patients suspected arrhythmia-related exercise such as ischemic heart disease or cathecolaminergic polymorphic ventricular tachycardia |
| 1 | B | In patients with documented ventricular arrhythmia, 12 leads ECG should be obtained during sinus rhythm for evaluation of underlying heart disease |
