Ventricular Arrhythmias

What initiates Premature Ventricular Complexes (PVCs)?

• A normal sequence within the ventricles

• An ectopic focal point within the ventricles

• A visible P wave

• A reduction in cardiac output

How is the QRS complex described in PVCs?

• Narrower than normal

• Not visible

• Wider than normal with an unusual shape

• Identical to a normal QRS complex

What symptom might individuals with benign PVCs experience?

• Increased cardiac output

• Palpitations or fluttering in their throat or chest

• Consistent heart rhythm

• Visible P wave

PVCs are classified as frequent if there are how many per minute?

• One to five

• Six or more

• Less than one

• Ten or more

What pattern is demonstrated by the tracing in the image?

• Trigeminy pattern

• Bigeminy pattern

• Uniform pattern

• Interpolated pattern

What does a unifocal PVC indicate in an ECG reading?

• Multiple irritable areas in the heart

• A single irritable area in the heart

• Normal sinus rhythm without any PVCs

• A flatline indicating no heart activity

What does the presence of multifocal PVCs indicate in an ECG reading?

• A) A single irritable area in the heart

• B) Multiple irritable areas in the heart

• C) A normal heart rhythm without any issues

• D) The presence of a heart block

What is the characteristic of an interpolated PVC?

• It causes a significant pause in the normal rhythm.

• It occurs with an interruption in the normal rhythm.

• It occurs with no interruption in the normal rhythm.

• It is followed by a compensatory pause.

What is the pattern of PVCs in Bigeminy?

• PVCs occur every beat.

• PVCs occur every third beat.

• PVCs occur every second beat.

• PVCs do not occur in a regular pattern.

What is Trigeminy in the context of Premature Ventricular Contractions (PVCs)?

• PVCs occur every second beat.

• PVCs occur every third beat.

• PVCs occur every fourth beat.

• PVCs occur randomly without a specific pattern.
