First of all when do you calculate an ventricular rate vs. an atrial rate? How do you know which one you want to calculate? (I know the SA node is in the right atrium and is the main pacemaker)
We are learning about ECG/EKG interpretation in class. One of the class of the class objectives is to calculate the rate for regular and irregular rhythms. I got the regular part down fine (count the # of QRS complexes in 6 seconds and X10, my teacher said this can not be used for irregular rhythms but "ECG made incredibly easy says it can be used for both...just not very accurate right?); its the irregular rhythms that confuse me. It just seems like unless it is a regularly irregular rate there is no way to determine an irregular rate unless you count for an entire min of strip; yet this is what one books says to count the # large boxes and divide into 300 or count the number of small boxes and divide into 1500; give a rate range (slowest and fastest rate)...so a range is sufficient when the teacher asks to calculate the rate of an irregular rhythm and only gives a 6 second strip?
