The ECG Roadmap
Doctors start by looking at the overall pattern of the ECG, like a bird's eye view of a city. They check the heart rate and rhythm, looking for any irregularities. It's like making sure all the traffic lights in the city are working properly. Next, they zoom in on specific areas, examining each wave and interval for clues about different parts of the heart.
Waveform Detective Work
Each part of the ECG waveform tells a story. The P wave shows atrial activity, the QRS complex reveals ventricular contraction, and the T wave indicates ventricular relaxation. Doctors analyze the shape, size, and timing of these waves. It's like being a detective, where every little detail could be an important clue about your heart's health.
Measuring for Meaning
Precise measurements are crucial in ECG interpretation. Doctors use special tools to measure intervals like PR, QRS, and QT. These measurements help diagnose conditions like heart block or long QT syndrome. It's similar to a tailor measuring fabric - every millimeter matters for a perfect fit.
