A racing heart, sudden dizziness, or unexplained fatigue are symptoms that may not be serious, but they potentially indicate heart problems. Knowing when to get an EKG can help you catch heart conditions early and take control of your health. Here is more information about when you might benefit from an EKG:
Understanding the EKG
An electrocardiogram, or EKG, is a painless test that records the electrical activity of your heart. Doctors use EKGs to detect a range of conditions, and the results often guide the next steps in your care. An EKG can help identify:
- Arrhythmias, or irregular heartbeats
- Coronary artery disease
- Previous or ongoing heart attacks
- Heart valve problems
- Structural abnormalities in the heart
The test works by placing electrodes on the skin to measure electrical impulses as the heart beats. Results are recorded as a wave pattern on a graph, and a doctor interprets the data to identify any irregularities.
Exploring Pain and Heart Palpitations
Chest pain is one reason a doctor orders an EKG. The pain can feel sharp, dull, or like pressure in the chest. It often radiates to the arm, jaw, or back. Chest pain has many possible causes, so an EKG helps rule out or confirm heart-related origins.
Heart palpitations are another key symptom. A palpitation feels like a fluttering, pounding, or skipping sensation that is located in the chest. These episodes are sometimes brief, but they can indicate an underlying arrhythmia that needs evaluation.
Identifying Breathing Difficulties and Dizziness
Unexplained shortness of breath, especially during mild activity or at rest, can be a sign that the heart is not pumping efficiently. Acknowledging this symptom and ordering an EKG allows a doctor to assess whether a cardiac condition is contributing to the breathing difficulty. Dizziness or lightheadedness that comes on suddenly may also warrant an EKG. The heart and brain are closely connected, and a drop in cardiac output can reduce blood flow to the brain. Fainting episodes, in particular, are a strong reason to seek an evaluation right away.
Reviewing Severe Fatigue Symptoms
Not all fatigue signals a heart problem, but certain patterns do raise concern. Fatigue that is persistent, unexplained, and accompanied by other symptoms may indicate the heart is under stress. These other symptoms may include swelling in the legs or difficulty breathing.
The heart works continuously, and when it struggles to maintain a normal rhythm or pump sufficient blood, the body compensates by redirecting energy away from other systems. Patients with heart conditions can experience exhaustion even after rest. That type of fatigue differs from the tiredness that follows a poor night’s sleep. An EKG can provide the data a doctor needs to determine whether the heart is functioning within a normal range.
Learn More About Heart Health
An EKG is a diagnostic tool, and it plays a role in understanding heart health. Chest pain, palpitations, breathing difficulties, dizziness, and unexplained fatigue are all symptoms that may prompt a doctor to recommend one. After an EKG, a doctor reviews the results and determines whether further testing is needed. Testing can include additional imaging or wearing a Holter monitor to track heart rhythm over time. If you want to learn more about heart health, consult a healthcare provider near you.
