Define the measurement of both the small and larger divisions on the graph paper used for rhythm strips.

The smaller box measures 1 mm in width and is equal to 0.04 seconds. The larger box is made of 5 smaller boxes, making it 5 mm in width and is equal to 0.20 seconds.

Describe the methods used to calculate the heart rate of a rhythm strip.

Using a caliber, measure the distance between two R waves. Then, keeping that measurement on the caliber, measure each R to R interval to make sure they are all equal. If all the QRS complexes are of equal distance between each other, measure the number of small boxes between the R waves and divide this number into 1500. If the rhythm is ...

- Abstract Cardiovascular diseases such as heart failure are some of the leading causes of mortality and morbidity with Australia being one of the country’s most greatly affected (McLean, Esclick & Coats, 2006). An area of interest in the pathology of heart failure is the significance that polymorphisms of adrenergic receptor genes have on the outcomes of patients with heart failure. Single-nucleotide polymorphisms or SNPs that occur in the genes that encode for adrenergic receptors are known to have various physiological and functional consequences. Specifically, the β1-adrenergic receptors have a crucial role in the regulation of heart rate and ...

Patient Three

A 30-year-old woman presented to her Family Medicine physician with complaints of increased sweating (even in relatively cool surroundings), diarrhea, unexplained weight loss, insomnia, and feelings of anxiety.
