Calcium channel blockers are medications prescribed for hypertension (high blood pressure) and chest pain, although they may also be used to treat migraine headaches or other conditions. Calcium channel blockers target the movement of calcium into blood vessels and muscles in your heart. Your doctor may prescribe these medications so that your heart will have a larger supply of oxygen and blood. Calcium channel blockers can reduce your heart rate, making it important for you to check your pulse rate regularly. Unless your doctor recommends differently, check your pulse once daily at the same time every day.
Step 1
Place your non-dominant arm out in front of you, palm facing up.
Step 2
Place the first two fingers of your dominant hand on your other wrist, about one inch below the bend of your wrist and near the base of your thumb.
Step 3
Slide your fingers slightly toward the center of your arm, pressing gently and feeling for your pulse between your wrist bone and tendon. Move your fingers as needed to find your pulse; you may also need to vary the amount of pressure you are applying.
Step 4
Begin counting the number of beats. Count for 15 seconds and multiply by 4 if your pulse rate is regular; if it is irregular, count for a full 60 seconds.
Step 5
Record your pulse rate to create a record you can show your doctor at your next appointment.
Step 6
Call your doctor immediately if your pulse rate is too high, too low, or if it is noticeably different from previous readings, and you are experiencing symptoms of illness.
Tips and Warnings
- Finding your pulse becomes easier with practice. If you have problems taking your pulse, talk to your doctor about taking your pulse on your neck or using a pulse rate monitor. Maintain proper oral hygiene and see your dentist regularly; calcium channel blockers can cause swelling, bleeding or tenderness of the gums.
- Take your calcium-channel blocker at the same time every day. Do not stop taking your calcium-channel blocker without talking to your doctor; stopping these medications abruptly can cause serious side-effects, and you will usually be instructed to gradually decrease your dosage.
