Revision as of 15:12, 4 April 2012
Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-In-Chief: Lakshmi Gopalakrishnan, M.B.B.S. [2]
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 in Congestive Heart Failure
Low QRS Voltage: The EKG often shows low QRS voltage. There are two broad underlying causes of low QRS voltage in the patient with heart failure:
- Electrically inert myocardium due to a loss of viable myocardium
- Infiltration of the myocardium (myxedematous, Chagas disease)
In alphabetical order the differential diagnosis of causes of low QRS voltage in the patient with heart failure includes:
Poor R wave progression: Poor R wave progression in the precordial leads may be secondary to a prior myocardial infarction but can also be observed in the absence of a prior myocardial infarction in the patient with heart failure.
Left bundle branch block (LBBB): Left bundle branch block (LBBB) can be observed in both ischemic and non-ischemic cases of heart failure.
Left ventricular hypertrophy: Changes of left ventricular hypertrophy consistent with a history of hypertension can be seen
Left atrial enlargement: Dilation of the left atrium can occur in congestive heart failure and the accompanying EKG abnormalities can be observed on the EKG.
Non-specific ST segment and T wave changes: T wave and ST segment inversions and flattening can be observed in heart failure.
