Which of the following is a common cardiovascular procedure?

Pacemaker insertion is recognized as a common cardiovascular procedure because it directly addresses issues related to the heart's electrical conduction system. This procedure involves placing a device that helps regulate abnormal heart rhythms, providing support for patients with arrhythmias like bradycardia (slow heart rate) or heart block. The pacemaker sends electrical impulses to stimulate the heart to maintain an adequate heart rate, which is crucial for proper blood flow and overall cardiovascular health.

In contrast, the other procedures mentioned focus on different body systems. A colostomy involves creating an opening for the colon, typically as a treatment for gastrointestinal issues. A hysterectomy is a surgical procedure to remove the uterus for gynecological conditions. Gastric bypass is a weight-loss surgery aimed at treating obesity. None of these procedures pertain to the cardiovascular system, highlighting why pacemaker insertion is the correct choice in this context.
