A skipped heartbeat often happens when an extra beat comes early, followed by a brief pause and a stronger beat. Learn why premature beats occur, common triggers, when they are usually harmless, and which symptoms should prompt medical assessment.

Blood pressure naturally changes throughout the day with sleep, activity, stress and other factors. Learn why readings can vary, how to measure blood pressure correctly at home, and why the pattern over time matters more than a single reading.
