What does the heart have to do to compensate for a hole between the two ventricles? Which of the following components of an ECG represents ventricular depolarization? a. P wave b. QRS complex c. T wave d. PQ interval Explain the cardiac cycle and the heart sounds. ...
Atrial systole extends until the QRS complex, at which point, the atria relax. The QRS complex represents depolarization of the ventricles and is followed by ventricular contraction. TheT waverepresents the repolarization of the ventricles and marks the beginning of ventricular relaxation. What does d...
Automatic detection of the QRS complex, P wave, and T wave, represents one of the most important steps towards identification of pathology in an ECG4. The correct detection of these ECG components is crucial for accurate diagnoses. Detection of the P wave is the most complicated part of the ...
Does the amplitude of QRS complex change with the pulse amplitudes? Why or why not? Explain why a pulse can only be detected in an artery and not in a vein. Why are the ventricles located together at the apex of the heart? If the heart beating faster means that more vital substances ...
C wave: QRS complex, tricuspid bulging into RA X descent: when tricuspid valve is pulling down during the latter stage of ventricular systole; indicating emptying of blood from ventricle. Central Venous Pressure (CVP) V wave: after T wave, RA filling before tricuspid opening. ...
What happens to the QRS complex on an electrocardiogram when the heart rate increases? In the ECG pattern of heart conduction, why is there no deflection of the atrial depolarization? O Because the 2 atrial chambers are in systole O Because the ventricl...
How does the ECG vary and what is occurring during these conditions: junctional rhythm, second-degree heart block, and ventricular fibrillation? ECG: The ECG variation can be represented by the reduced or increased amplitude of T-waves...
Explain cardiac conduction in the heart. How would heart function be affected if the AV valves did not completely close during ventricular contraction? What happens to the duration of the QRS complex on an electrocardiogram when heart rate increases due to exercise? What involves uncoordinated atrial...
The QRS-complex of the ECG is generated by the depolarization of the AV-Nodes and ventricular myocardium. A. True. B. False. Turbulent flow can occur in the heart in patients with sinus bradycardia. True False True or False. Closure of the atrioventricular valves occurs ...
the V sense test might not be able to reliably determine the order in time of sensed LV and RV QRS complexes and hence might not be able to reliably determine the value of Δ. (A QRS complex is a portion of an intracardiac electrogram that represents intrinsic ventricular depolarization. Wi...
