In an era of all-encompassing digitization, hospitals, practices, and medical practitioners are experiencing a gradual, yet pervasive, shift toward a more modern type of medicine – based in artificial intelligence and machine learning instead of the classical healthcare model.
Thinking about your health means understanding your heart health, and paying attention to measures like cholesterol, blood pressure, and triglycerides. There is one more to add to the list: heart rate variability.
“Heart rate variability is the variation in the time between each heart beat,” explains John P. Higgins, MD, MBA, a sports cardiologist at McGovern Medical School at the University of Texas Health Science Center at Houston. This is different than your heart rate, which is measured by the number of times your heart beats per minute. And unlike your heart rate, which you can calculate by counting your pulse, heart rate variability is measured at the doctor’s office with an electrocardiogram (ECG or EKG) test that records the electrical activity of your heart.
