Which statement about beta blockers is NOT correct?

The statement that beta blockers increase exercise capacity in all patients is not accurate. While beta blockers are known to help manage heart conditions such as hypertension and arrhythmias, they can actually impair exercise capacity in many individuals. This is primarily because beta blockers reduce the heart rate response to exercise, making it harder for patients to reach target heart rates that would typically enhance physical performance and endurance.

In contrast, the other statements are correct. Beta blockers do typically have names ending in "lol", they can indeed mask the symptoms of hypoglycemia by blunting the physiological responses usually indicative of low blood sugar levels, and it is important to monitor maximum heart rate during exercise in patients taking these medications to ensure their safety and effectiveness of cardiac response.
