What does an EKG show?
1. An EKG can reveal an arrhythmia (an abnormal heart rhythm).
Why do we need an EKG?
Your heart is a hard-working muscle that requires plenty of oxygen in order to stay strong and function properly. However, due to blockages or constrictions in the coronary blood vessels, the heart can experience ischemia, a dangerous state in which the cardiac tissue is underperfused. If your heart experiences prolonged ischemia, the muscle can actually start to die, leading to heart failure and even death. An EKG is a useful tool that helps medical providers evaluate how much oxygen your heart is getting and intervene immediately if your heart is ischemic to prevent catastrophic complications.

These are “silent” heart attacks that don’t cause any noticeable symptoms. You may wonder how an EKG shows a previous heart attack? Plausible by recording the inconsistent flow of blood.
Can An Ekg Forecast Future Heart Attack?
Researchers found that patients will have an abnormal EKG if they have atherosclerotic disease or multiple risk factors for heart attack. If ECG is normal, can you still have heart problems? The answer is yes. EKG or ECG alone is not a perfect predictor of a future heart attack of a low-risk person. So it is possible to get a heart attack even after getting a normal EKG. The reason is, it can not show asymptomatic blockage in your arteries. ELG works best when you combine it with blood tests or imaging tests. At MyConciergeMD, the team of doctors and technicians are happy to assist you with their expertise in detecting a heart attack.
