If a rhythm is IRREGULAR, the best way to determine rate is to:
◦ count the number of large squares between two R waves and divide that into 300.
◦ use a rate meter.
◦ count the number of small squares between two R waves and divide that into 1500.
◦ count the number of QRS complexes in a 6-sec strip and multiply by 10.

Which of the following best describes a "lost" P wave?
◦ One that is visible but highly irregular.
◦ One that is there one minute but gone the next.
◦ One that can't be counted because it happens too quickly.
◦ One that is obscured because it falls on other waves.

The P waves are the first waves you should look for when analyzing a rhythm strip because:
◦ they are usually very regular and thus easy to find.
◦ they are the biggest and thus most visible.
◦ they are the most important for diagnosing heart disease.
◦ they always have a constant relationship with the waves around them.
