Background and Purpose: Extracorporeal shock wave lithotripsy (ESWL) is initial treatment of choice for most calculi in the kidney. Although ESWL has many side effects one of which is cardiac arrhythmia, occurring mostly in non-synchronized mode. The aim of this research was to determine the effect of extracorporeal shock wave lithotripsy on electrocardiogram changes in patients with renal stone. Methods: This quasi-experimental study was carried out on 75 patients with renal stone who were selected by non-probability and convenience sampling. Then electrocardiograph was obtained from participants before, during and after lithotripsy. The relationship between ESWL-associated arrhythmia and autonomic neural activity was evaluated by heart rate spectral analysis. Electrocardiogram changes were interpreted and the data were analyzed in SPSS and SAS using chi-square, independent t-test, paired t-test, McNemar, Cochrane, One-way ANOVA and general linear model. Results: ESWL was found to elicit new or worsened electrocardiogram changes in 66.7 percent patients with no previous cardiac disease. A statistically significant correlation was demonstrated between the presence of ventricular premature contractions and analgesic drugs (p

Background and Purpose: One probable sources of error blood pressure measurement can be the cross-leg seating position but research findings in this regard are contradictory. Therefore the present study was designed to investigate the effect of crossing legs while measuring the blood pressure on the reading of blood pressure in patients with hypertension. Methods and Materials: The quasi- experimental study involved 90 patients selected through purposive sampling from among the population of patients with primary hypertension admitted to Internal and Cardiac Clinics of Vase'ee Hospital in Sabzevar Iran. Patients blood pressure was measured according to a written protocol in three steps: first sitting with both feet straight on the floor then sitting with crossed legs and finally sitting with both feet straight on the floor (as in the first step). Conventional stethoscope and sphygmomanometer were used for measurements; t- test was used for data analysis in SPSS. Results: Crossing legs while measuring blood pressure increased systolic bp by 6.81 mmHg (from 144.43±21.782 to 156.24± 22.082) and diastolic bp by 3.12 mmHg (from 89.06± 13.610 to 92.18± 14.920). Mean systolic bp when the third step of the protocol was adopted reduced 9.59 mmHg (from 156± 22.082 to 146.66± 22.438) and diastolic bp reduced by 3.53 mmHg (from 92.18±14.920 to 88.64± 14.839). Conclusion: According to the findings blood pressure reading increases in patients with hypertension when they take a seated cross-leg position during bp measurement.
