In individuals with suspected<unk> , a serum<unk>  concentration, serum potassium concentration, creatinine, BUN, and serial electrocardiograms is obtained. ECG An ECG showing<unk>  with the classic "scooped out" ST segment In<unk> , the finding of frequent premature ventricular beats (PVCs) is the most common and the earliest dysrhythmia. Sinus bradycardia is also very common. In addition, depressed conduction is a predominant feature of<unk> . Other ECG changes that suggest<unk>  include bigeminal and trigeminal rhythms, ventricular bigeminy, and bidirectional ventricular tachycardia. Blood test The level of<unk>  for treatment is typically 0.5-2 ng/mL. Since this is a narrow therapeutic index,<unk>  overdose can happen. A serum<unk>  concentration of 0.5-0.9 ng/mL among those with heart failure is associated with reduced heart failure deaths and hospitalizations. It is therefore recommended that<unk>  concentration be maintained in approximately this range if it is used in heart failure patients. High amounts of the electrolyte potassium (K+) in the blood (hyperkalemia) is characteristic of<unk> .<unk>  increases in individuals who have kidney impairment. This is most often seen in elderly or those with chronic kidney disease or end-stage kidney disease.
