A resting electrocardiogram (ECG or EKG) is a non-invasive test that measures the electrical activity of your heart. It provides valuable information about heart function.
During a resting ECG, you will be asked to remain calm while leads are connected to your chest, arms, and legs. These electrodes capture the electrical signals from your heart to a machine that produces a graph of your heartbeat called a waveform.
A resting ECG can identify various heart conditions, including arrhythmias, heart block, and coronary artery disease. Healthcare providers can interpret the results of your ECG to assess the health of your heart.
Interpreting ECGs from Exercise Stress Tests
During an exercise stress test electrocardiogram, a series of physiological signals are recorded as the patient performs physical activity. This allows physicians to evaluate the heart's function during higher workload. Decoding of these ECG patterns can reveal important information about coronary artery disease, rhythm abnormalities, and other underlying heart problems.
Common findings during an exercise stress test ECG include heart rate elevation, bundle branch blocks, and ventricular pre-excitation. A skilled cardiologist can analyze these changes in the context of the patient's physical exam to provide a comprehensive diagnosis of their cardiovascular health.

Clinical Correlates of Vital Signs
Correlating vital signs with electrocardiographic (ECG) findings provides valuable clues into a patient's overall health status. Monitoring parameters like heart rate, blood pressure, and respiratory rate in conjunction with ECG waveform analysis can help the identification of subtle abnormalities. For example, tachycardia may be associated with ST-segment elevation on an ECG, suggesting myocardial ischemia. Conversely, hypotension commonly presents as sinus bradycardia, indicating a potential autonomic nervous system dysfunction.
- Additionally, the correlation between vital signs and ECG findings can guide clinical decision-making.
- Healthcare providers can use this information to modify treatment plans, track patient response, and possibly reduce negative consequences.
Typical 12-Lead Electrocardiogram Findings
A resting 12-lead electrocardiogram provides a snapshot of the electrical activity of the heart. Healthy findings on an ECG demonstrate sinus rhythm with regular heart rate and consistent patterns. Occasionally, minor variations in QRS shape may be observed, which can be non-significant.
Additionally, an ECG may reveal abnormalities that indicate underlying health problems. These indicators may include prolonged PR segments, abnormal Q waves, ST shifts, and widened widths. Assessing these findings requires skilled knowledge and consideration of the patient's clinical presentations.
ECG Analysis: Stress vs. Rest
An electrocardiogram (ECG) is a valuable tool for assessing the electrical activity of the heart. When analyzing an ECG, detecting differences between stress and rest states can provide crucial clues about heart function and potential underlying conditions. During stress, the body releases hormones that speed up heart rate and change its rhythm. Simultaneously, ECG readings may show increased amplitude of the QRS complex, indicative of larger electrical signals generated by the ventricles as they pump more forcefully. In contrast, during rest, the heart rate and amplitude of ECG waves decrease. This variation in ECG patterns illustrates the dynamic nature of cardiac function and its response to physiological demands.
