A variety of ways to calculate heart rate from an ECG may be used. The quickest way to calculate heart rate on a rhythm strip is: Count the number of large squares between one R-R interval, and divide this number into 1500. Calculate the number of QRS complexes in 1 minute Count the number of R-R intervals in 6 seconds, and multiply by 10 Count the number of small squares between one R-R interval, and multiply this number by 300.

The right and left atria of the heart look alike and perform similar functional demands. The right and left ventricle are very different, structurally and functionally. Why are the atria similarities and the difference in the ventricles significant in the role they play in the functional activity of the heart? How would these differences be manifested on an EKG, with details given to the P wave and QRS complex?

/An elderly man presents to the emergency department with chest pain. He has a history of stable angina and recent onset dizbetes mellitus, but now the chest pain comes on with less exertion and takes longer to g0 away. An ECG and cardiac enzymes are ordered. If this man has unstable angina, what are the expected findings on ECG and cardiac enzyme testing? (A) Delta waves on the ECG and elevated cardiac enzyme levels (B) Low voltage ECG and elevated cardiac enzyme levels () No changes on ECG and elevated cardiac enzyme levels (D) ST-segment depressions on ECG and normal cardiac enzyme levels (B) ST-segment elevations with Q waves and Normal cardiac enzyme levels
Conceptualize in Color Electrocardiogram Color each part of the ECG waveform shown bere as suggested. • P wave: Green • QRS complex: Yellow • PR interval: Purple • ST segment: Brown •T wave: Blue Next, link each part of the waveform to the cardiac activity it represents by underlining each particular statement with the color you sused in the waveform. For example, if you colored the P wave green, underline in green the statement describing what the P wave represents. 1. This part of the waveform represents ventricular repolarization. 2. This part of the waveform represents atrial depolarization. 3. This part of the waveform represents the time it takes for the cardiac impulse to travel from the atria to the ventricles. 4. This part of the waveform represents ventricular depolarization. 5. This part of the waveform represents the end of ventricular depolarization and the beginning of ventricular repolarization. 192 Chapter 15 Heart
