In the present study, our first aim was to assess the capability of body surface potential mapping (BSPM) QRS area analysis for detection and quantification of pressure overload-induced LVH compared ...

The first six QRS complexes shown in Figure 2 are regular at a rate of 150 beats/min. The tachycardia terminates abruptly, and the next QRS complexes are regular, at a rate of 90 beats/min. All of the ...

The QRS complex consists of the Q wave, the R wave and the S wave. The QRS complex comes after the P wave when the SA nodal action potential travels through the AV node to the ventricles to cause ...
