The changing role of ECG stress testing
ECG stress testing plays a key role in the evaluation of cardiac patients¹, and yields valuable prognostic information², which is invaluable in determining treatment and management of patients.

Let's explore some of those measurements
T-Wave Alternans in Stress testing
T-Wave Alternans (TWA) is an electrophysiological phenomenon that is evident in the ECG. TWA enables physicians to identify an often-missed pattern variation that may indicate a high level of SCD risk and helps support earlier treatment decisions. Performing a TWA test is useful for patients who have had an MI, family history of MI and/or SCD, on beta-blockers, using an antiarrhythmic drug, or will be using an antiarrhythmic drug. T-Wave Alternans can be collected during a standard Holter or ECG exercise stress test.

What about Dynamic Versus Pharma ECG Stress Testing?
Information gained from tests based on physical exertion reveal more about each patient's functional capacity, exercise tolerance, and factors resulting in symptoms.¹
