What is the difference between heart rate and ventricular rate?
On an ECG the heart rate will match both ventricular rate and atrial rate if the heart is normal. If people have atrial fibrilation then the ventricular rate will be used on the ECG to work out the rate of the ventricular contraction and vice-versa with ventricular fibrilation. Usually both atrial and ventricular rates match so if the atria contracts at 70 BPM the ventricles will beat at 70 BPM. It is possible for the ECG machine to work out atrial or ventricular rate if needs be. Usually, however, if the ECG machine just displays heart rate then both ventricular and atrial rates match.
What effect does atropine have on heart rate?
Ventricular fibrillation, and supraventricular or ventricular tachycardia.
What is the difference between ventricular and atrial rate?
The atrial rate refers to the number of electrical impulses originating from the atria, while the ventricular rate is the number of impulses generated that reach the ventricles and trigger contraction. In a normal heart, these rates are typically equal, but in certain arrhythmias, such as atrial fibrillation, the atrial rate may be significantly higher than the ventricular rate. This discrepancy can affect cardiac output and overall heart function. Understanding both rates is crucial in diagnosing and managing various cardiac conditions.
Does the atrial rate equal the ventricular rate in the ECG tracing?
yes
Is there a pulse rate in ventricular fibrillation?
ofcourse.
What does nonsustained ventricular tachycardia mean?
Nonsustained ventricular tachycardia is elevated heart rate originating in the ventricles that stops on its own.
When heart rate is increased the time of ventricular filling is?
. . . decreased.
What portion of the ECG indicates ventricular repolarization?
The portion of the ECG that indicates ventricular repolarization or recovery is the t wave. It is the wave found after the QRS complex (Ventricular depolarizaton) in a normal ECG
What is normal left ventricular ejection fraction as a percentage?
According to my Cardiologist 50-70% is normal.
What is the normal blood pressure recorded during the ventricular systole?
cardiac cycle Normal is less than 120 (mmHg)
What is the physiology of ventricular tachycardia?
A rapid heart rate can originate in either the left or right ventricle. Ventricular tachycardia which lasts more than 30 seconds is referred to as sustained ventricular tachycardia
How many seconds does ventricular contraction last?
The normal time of ventricular contraction depends on the heart rate. The QT segment represents the ventricular contraction on an ECG exam. The corrected QT segment is 0.45 seconds for men and 0.46 seconds for women.
