Summary
Tardokinesia, an abnormal slowness of left ventricular wall contraction, was quantitatively analyzed. This finding may serve as an early indicator of ischemic heart disease.
Area of Science:
- Cardiology
- Radiology
- Medical Imaging
Background:
- Tardokinesia is defined as abnormal slowness of left ventricular (LV) wall contraction.
- Analyzing LV regional wall motion is crucial for understanding cardiac function.
Purpose of the Study:
- To quantitatively define and analyze tardokinesia.
- To assess the potential of tardokinesia as an early indicator of ischemic heart disease.
Main Methods:
- Quantitative analysis of LV regional wall motion using cine left ventriculograms from 44 patients.
- Superimposition of a polar grid on ventricular tracings to measure wall motion at 30 points.
- Calculation of location, speed, and acceleration for each measured point.
Main Results:
- Two cases of tardokinesia were identified in the study cohort.
- The quantitative method allowed for precise measurement of LV wall motion abnormalities.
Conclusions:
- Tardokinesia can be quantitatively assessed using cine left ventriculography.
- Tardokinesia may represent a sensitive early sign of ischemic heart disease, warranting further investigation.
