Electrocardiograms (ECGs) are powerful diagnostic tools used to detect potentially life-threatening heart conditions that may otherwise go unnoticed. Dr. Ian Weisberg, a leading cardiologist, emphasizes the importance of ECGs in identifying dangerous cardiac issues early, before they lead to severe complications or even death. Through analyzing the heart's electrical activity, ECGs can uncover hidden risks and allow for timely intervention.
An ECG measures the electrical impulses that trigger each heartbeat. The resulting graph provides a detailed picture of the heart’s rhythm and function. Key components of the ECG waveform include the P wave, QRS complex, and T wave, each representing different phases of the heart’s electrical cycle. Dr. Ian Weisberg explains that abnormalities in these segments can indicate underlying heart disease, arrhythmias, or other dangerous conditions that require immediate attention.
