The ventricular rate refers to the number of times the ventricles of the heart contract per minute.
The ventricular rate is an important indicator of heart function and rhythm. Several factors can influence it:
-
Atrioventricular Conduction: The degree to which electrical signals pass from the atria to the ventricles significantly impacts the ventricular rate. According to the provided reference, the ventricular rate depends on the degree of atrioventricular conduction.
-
Normal Conduction: With normal atrioventricular conduction, the ventricular rate typically varies between 100 and 180 beats per minute.
-
Atrioventricular Block: Slower ventricular rates may suggest a higher degree of atrioventricular block, which is a disruption in the electrical signals traveling from the atria to the ventricles.
-
Medications: Certain medications, such as digoxin, can also slow down the ventricular rate.
Here's a table summarizing typical ventricular rate ranges and their potential implications:
| Ventricular Rate (beats/min) | Possible Implication |
|---|---|
| 100-180 | Normal conduction |
| Below Normal | Higher degree of atrioventricular block, medication side effect |
