An EKG is a versatile diagnostic tool used in various medical circumstances to assess the electrical activity of the heart and detect potential cardiac issues. Some of the situations when an EKG is used include: • Routine check-ups - EKGs are commonly included in regular health check-ups for adults, especially those with risk factors like high blood pressure, diabetes, or a family history of heart disease. • Fitness screening - Individuals with certain risk factors who are participating in rigorous physical activity are advised to undergo an EKG to rule out underlying heart conditions. • Chest pain - When a person experiences chest pain or discomfort, an EKG can be used to determine if it's due to a heart attack or other cardiac problem. • Shortness of breath - If breathing difficulties are suspected to be heart-related, an EKG can help pinpoint the underlying cause. • Palpitations - EKGs can identify irregular heartbeats, known as arrhythmias, that cause palpitations. • Monitoring heart conditions - This method is often used to monitor patients with heart disease, such as heart attacks, heart failure, or pacemaker implantation. • Medication monitoring - Some medications affect heart rhythms, so in these cases, EKGs are used to monitor the potential impact. • Preoperative evaluation - An EKG screening is often performed before surgery to assess cardiac risk and ensure the patient can safely undergo anesthesia. • Post-heart attack - EKGs are used after a heart attack to assess damage and plan treatment.
