However, if its caused by a congenital or chronic health condition, it might require a permanent pacemaker to help manage symptoms. Usoro and colleagues reported that among 6,440 participants from the Third National Health and Nutrition Examination Survey, low voltage was detected in 1.4% (n = 89) of participants, and the mortality rate among those individuals was almost twice that compared with those without low voltage (51.1 versus 23.5 events per 1,000 person-years, p < .01).10 A similar finding has been reported among hospitalized patients.11,12 Thus, low voltage is truly a warning sign for the clinician. The Costs of ECG Misdiagnosis due to Poor R-Wave Progression. There are several potential causes of LAD. A sinus pause occurs when the sinoatrial node fails to initiate an impulse. The author has disclosed no financial relationships related to this article. daily for hypertension, mesalamine 800 mg P.O. The ECG is generally regarded as abnormal if the patient has bradycardia (slow beat activity) of less than 60 or tachycardia (rapid beat activity) of more than 100 unless the doctor has specific reasons to believe the results are defective or incorrect. Hypokalemia is associated with prolongation of the QT interval and T waves that are lower in amplitude.17 In this patient, the T wave appears wide with a low amplitude, and the P wave is also dampened. A few other tests may be performed as part of the diagnostic process. ECG criteria follows: Regular rhythm with ventricular rate slower than 50 beats per minute. Low voltage is defined as a QRS amplitude of 5 mm (0.5 mV) or less in all of the frontal plane leads and 10 mm (1.0 mV) or less in the precordial leads.
