Cardiac disease is a concern as people age. In fact, heart problems are fairly common in men over the age of 50 but are increasingly affecting younger adults, regardless of gender. This is attributed, at least partially, to more sedentary and stressful lifestyles and unhealthy habits. But genetics may also play a role.
Electrocardiogram (ECG) is a common medical test for assessing cardiac function by measuring the electrical activity of the heart, although other tests may also be done. ECG is considered a fairly routine and sufficient indication of heart health and is performed with 3, 5, 12, or 15-lead ECG/EKG machines.
Interestingly, it’s also possible to design a low-cost ECG machine using Arduino and an AD8232 ECG sensor.
