Overview

Although there is no diagnostic criteria of congestive heart failure on the EKG, there may be signs of the underlying cardiac cause(s) of congestive heart failure.

Electrocardiographic Abnormalities

• The EKG often shows low voltage. The differential diagnosis of low voltage on the EKG includes amyloid.
• Poor R wave progression in the precordial leads may be secondary to a prior myocardial infarction but can be observed in the absence of a prior myocardial infarction.
• Left bundle branch block (LBBB) can be observed in both ischemic and non-ischemic cases.
• Left ventricular hypertrophy consistent with a history of hypertension can be seen
• Left atrial abnormality
• Non-specific ST segment and T wave changes
