[Precordial heart beats in myocardial infarct (clinical and electrocardiographic study in 40 cases)]
Insights
Cinetocardiograms reveal abnormal systolic movements in myocardial infarction patients. These findings correlate with palpation, ECG, and radiologic studies, aiding in assessing myocardial disturbance severity.
Area of Science:
- Cardiology
- Diagnostic Imaging
Context:
- Myocardial Infarction (MI) diagnosis and assessment.
- Utilizing precordial cinetocardiograms (K1-K6) in patient studies.
Purpose:
- To compare cinetocardiogram findings with palpation, ECG, and radiologic studies in MI patients.
- To evaluate the diagnostic value of cinetocardiograms in recent and old myocardial infarctions.
Summary:
- Studied 40 MI patients (10 recent, 30 old) using precordial cinetocardiograms (K1-K6).
- Abnormal systolic movements were observed in all recent infarcts (50% palpable) and 90% of old infarcts.
- Findings correlate with precordial palpation, ECG, and radiologic studies, indicating severity of myocardial disturbance.
Impact:
- Cinetocardiograms can help assess the severity of myocardial damage in infarction.
- Abnormal systolic movements' extent correlates with disturbance severity.
- Aneurismectomy may resolve these phenomena, suggesting therapeutic implications.
Abstract:
The precordial K1 to K6 cinetocardiograms in 40 patients with Myocardial Infarction (10 recent and 30 old) were studied. These were compared with the findings of the precordial palpetion, electrocardiograms, and the radiologic studies. In the recent infarcts, all the patients presented abnormal systolic "annoyances", 50% of which were palpable. In the old infarcts, 90% had abnormal cinetocardiograms and 63% had pathological precordial beats. The anterior infarcts tend to present "sounds" more to the right of the precordium than the posterior-inferiors. The diffuse cardiac hypokinesia may give normal cinetocardiograms. The severity of the myocardial disturbance is directly related to the precordial extension occupied by the abnormal systolic "annoyances". An aneurismectomy may cause the disappearance of the pathogenesis of these phenomena.
