EKG Interpretation for DUMMIES
The Paramedic Coach・2 minutes read
The EKG waveform consists of the P wave representing atrial depolarization, the QRS complex reflecting ventricular depolarization and contraction, the T wave signifying ventricular repolarization, with intervals like PR, ST, and QT key in measuring electrical activity and diagnosing heart conditions. Electrodes for EKG placement are color-coded and correspond to specific body parts, with optimal placement on the humeral heads and close to the ankles, crucial for accurate readings.
Insights
- The P wave on an EKG signifies the Atria depolarizing, while the QRS complex represents the ventricles depolarizing, crucial for understanding the heart's electrical activity.
- The ST segment, extending from the end of the S wave to the start of the T wave, is vital for diagnosing heart attacks, emphasizing the importance of this portion of the EKG for medical professionals.
