Overview
Stress testing is used for risk stratification and diagnosis of coronary artery disease.
Electrocardiogram
Exercise EKG/Stress EKG is preferred initial test unless the patients have uninterpretable EKG not in a condition to exercise. Few uninterpretable EKG conditions are
- WPW syndrome
- > 1 mm of ST depression at rest
- Left bundle branch block
- Ventricular pacing
- Resting abnormalities of ST segment and T waves.
Prognostic Markers: Exercise EKG
- In ECG recording
- Maximum ST elevation
- Number of leads showing changes
- Duration for onset of ST segment changes
- Duration for ST segment change recovery
- ST/HR indices
- Occurrence exercise induced ventricular arrhythmia
- Hemodynamic markers
- Maximum heart rate, blood pressure, RPP
- Exertional hypotension
- Chronotropic incompetence
- Heart rate recovery
- Exercise capacity
- Duration
- Workload
- Ischemia
- Angina
- Time of onset
