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.

Electrocardiogram

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:
  1. Electrically inert myocardium due to a loss of viable myocardium
  2. 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.

2009 ACC/AHA Focused Update and 2005 Guidelines for the Diagnosis and Management of Chronic Heart Failure in the Adult (DO NOT EDIT) [3][4]

Electrocardiogram Assessment of Patients Presenting With Heart Failure (DO NOT EDIT) [3][4]

Class I
"1. Twelve-lead electrocardiogram and chest radiograph (PA and lateral) should be performed initially in all patients presenting with heart failure. (Level of Evidence: C) "
Class III (No Benefit)
"1. Routine use of signal-averaged electrocardiography is not recommended for the evaluation of patients presenting with heart failure. (Level of Evidence: C) "
Class IIb
"1. Holter monitoring might be considered in patients presenting with heart failure who have a history of myocardial infarction and are being considered for electrophysiologic study to document ventricular tachycardia inducibility. (Level of Evidence: C) "
