Blood Pressure and Heart Rate Calculator
Understanding your blood pressure and heart rate is crucial for monitoring your cardiovascular health. Blood pressure is the force of blood pushing against the walls of your arteries. It's measured in millimeters of mercury (mmHg) and is given as two numbers: systolic pressure (the top number, when your heart beats) and diastolic pressure (the bottom number, when your heart rests between beats). Heart rate, also known as pulse, is the number of times your heart beats per minute (bpm).
High blood pressure (hypertension) can increase your risk of heart disease, stroke, and other health problems. Low blood pressure (hypotension) can sometimes cause dizziness or fainting. A normal resting heart rate for adults typically ranges from 60 to 100 bpm, but this can vary. Athletes, for example, may have lower resting heart rates.
This calculator helps you log and see your readings. While it doesn't diagnose conditions, it's a useful tool for tracking your numbers over time. Always consult with a healthcare professional for diagnosis and treatment advice.
