What does poor R wave progression mean on an EKG?

Poor R Wave Progression Overview Poor R-wave progression (PRWP) is a common ECG finding that is often inconclusively interpreted as suggestive, but not diagnostic, of anterior myocardial infarction (AMI). PRWP is defined by R wave height ≤ 3 mm in V3.

What is good R wave progression?

The R wave should progress in size across leads V1 to V6. Normally, in lead V1, there is a small R wave with a deep S wave; the R-wave amplitude should increase in size with the transition zone, normally in leads V2 to V4.

What is an R wave in an ECG?

The QRS complex is made up of three waves. These waves indicate the changing direction of the electrical stimulus as it passes through the heart's conduction system. As you can see from the diagram, the R wave represents the electrical stimulus as it passes through the main portion of the ventricular walls. ...

What causes abnormal R wave progression?

Recent studies have shown that poor R-wave progression has the following four distinct major causes: AMI, left ventricular hypertrophy, right ventricular hypertrophy, and a variant of normal with diminished anterior forces. Standard ECG criteria that identify and distinguish these causes have been developed.

Should I be concerned about poor R wave progression?

Poor R-wave progression is a common ECG finding that is often inconclusively interpreted as suggestive, but not diagnostic, of anterior myocardial infarction (AMI).

Is poor R wave progression bad?

Poor R wave progression is used as an interpretative term in clinical electrocardiography to infer that the precordial R wave voltage is abnormal, most often secondary to previous ischemic damage. Specific definition and predictive value of the term are, however, lacking for most clinical settings.

Can poor R wave progression be normal?

Electrocardiographic poor R wave progression (PRWR) is found in patients with anterior myocardial infarction, left ventricular hypertrophy and right ventricular hypertrophy, and is also seen in apparently normal individuals.

Is poor R wave progression normal?

Electrocardiographic poor R wave progression (PRWR) is found in patients with anterior myocardial infarction, left ventricular hypertrophy and right ventricular hypertrophy, and is also seen in apparently normal individuals.

What happens when poor R wave progression?

Recent studies have shown that poor R-wave progression has the following four distinct major causes: AMI, left ventricular hypertrophy, right ventricular hypertrophy, and a variant of normal with diminished anterior forces. Standard ECG criteria that identify and distinguish these causes have been developed.

Should I worry about poor R wave progression?

Poor R-wave progression is a common ECG finding that is often inconclusively interpreted as suggestive, but not diagnostic, of anterior myocardial infarction (AMI).

What does R wave progression indicate?

Poor R wave progression refers to the absence of the normal increase in size of the R wave in the precordial leads when advancing from lead V1 to V6. In lead V1, the R wave should be small. The R wave becomes larger throughout the precordial leads, to the point where the R wave is larger than the S wave in lead V4.

Can poor R wave progression be reversed?

The electrocardiographic criteria correctly identified 75 percent (15) of 20 patients with poor or reversed R-wave progression without postmortem evidence of myocardial infarction, with only 12 percent (2/17) predictive error.
