Introduction
Poor R-wave progression typically indicates ventricular hypertrophy, which may result from hypertension causing excessive cardiac load. Myocardial damage or infection can lead to myocardial thickening, resulting in poor R-wave progression. Inadequate coronary blood supply leading to myocardial ischemia or necrosis can also cause myocardial thickening and subsequent poor R-wave progression. In addition, aortic stenosis and aortic regurgitation may also contribute to this condition.
Generally, poor R-wave progression usually indicates ventricular hypertrophy, which may be caused by conditions such as hypertension, myocarditis, or coronary heart disease. Specific analyses are as follows:
1. Hypertension
Long-term hypertension can overload the heart, leading to ventricular hypertrophy.
2. Myocarditis
Myocardial damage or infection can result in myocardial thickening, thereby causing poor R-wave progression.
3. Coronary Heart Disease
Inadequate blood supply from coronary artery disease leads to myocardial ischemia and necrosis, which can also cause myocardial thickening and result in poor R-wave progression.
In addition, aortic valve stenosis and aortic regurgitation can also lead to this condition. If this finding is observed, further evaluation combining other clinical manifestations and test results is necessary to determine the possible presence of cardiovascular disease.
