Sentence examples for Ventricular depolarization from inspiring English sources

Ventricular depolarization was recorded by electrocardiograph (V5 configuration) using commercially available hardware (Powerlab model ML, ADInstruments, Colorado Springs, USA) and software (LabChart 7.03, ADInstruments, Colorado Springs, CO, USA) sampled at 20 MHz.

ECG is composed of atrial depolarization (P wave), ventricular depolarization (QRS complex), and ventricular repolarization (T wave).

The ventricles are responsible for the QRS complex (during ventricular depolarization) and the T wave (during ventricular repolarization).

CONCLUSIONS In patients undergoing cardiac catheterization, short-term exposure to air pollution was associated with increased HR and delays in atrioventricular conduction, ventricular depolarization and repolarization.

As the QRS complex in ECG is associated with ventricular depolarization, therefore, accurate QRS detection is vital for interpreting ECG features.

The onset of ventricular depolarization defines the start of the pre-ejection period (PEP), which is commonly used as an index of myocardial contractility.

Now ICDs can easily distinguish the presence of greater numbers of atrial depolarizations than ventricular depolarizations in the case of supraventricular tachycardia (SVT), from the converse that is present in ventricular tachycardia (VT).

EIVAs were defined as frequent premature ventricular contractions (PVCs) constituting >10% of all ventricular depolarizations during any 30 second electrocardiogram recording, or a run of ≥3 consecutive PVCs during exercise or recovery.Results A total of 1256 patients (20%) died during follow-up.

Elliot and coworkers [ 38] found a 77% incidence rate of arrhythmias, including premature atrial or ventricular depolarizations, ventricular tachycardia, and transient RBBB in 116 patients undergoing PAC insertion, but this high rate was not associated with morbidity or mortality.

Previous studies indicated that the relationship exists between data of the interval between two ventricular depolarizations (R-R interval) deviation of the electrocardiography (ECG) and temperature environment during daily living and work for people living around Bangkok in Thailand (11).

Secondly, in contrast to experiments in spontaneously beating hearts to assess unprovoked arrhythmogenecity, both Scn5a+/Δ and WT hearts were subject to premature extrasystolic ventricular depolarizations using the established arrhythmia provocation protocol of PES.
