Study on the genesis of giant negative T wave in apical hypertrophic cardiomyopathy using a three-dimensional computer model. This model has successfully simulated normal QRST waves and changes characterizing some abnormal conditions. A model of apical hypertrophic cardiomyopathy was ... H Tsunakawa,D...
Existing nonlinear Bayesian filtering frameworks serve as an effective tool for the model-based filtering of noisy ECG recordings. However, since these methods are based on linear phase assumption, for some heart defects where abnormal waves only appear in certain cycles of the ECG, they are unable...
PTFV1 is calculated as the product of the duration and depth of the negative deflection of biphasic P-waves in the precordial ECG lead V1. (B) CMR feature tracking tracings of global longitudinal strain of the LA are used to calculate atrial strain parameters for ...
