Key result
Total QRS voltage significantly increased from admission (98.54 mm) to discharge (110.72 mm) and 3-month follow-up (111.72 mm) in patients with heart failure (p<0.001).
Why the study?
Does QRS voltage on ECG correlate with echocardiographic dimensions and clinical status in patients with heart failure?
Observational (n=100)
Does QRS voltage on ECG correlate with echocardiographic dimensions and clinical status in patients with heart failure?
p-value: p=<0.001
ECG QRS voltage amplitudes increase following heart failure treatment and inversely correlate with left ventricular dimensions and lower limb edema, suggesting utility in monitoring HF patients.

May aid noninvasive HF monitoring; hypothesis-generating and requires prospective validation before adoption.
Sadaka et al. (2012) conducted an observational in Heart failure (n=100). ECG voltage assessment was evaluated on Change in QRS voltage amplitude from admission to discharge and 3-month follow-up (p=<0.001). Total QRS voltage significantly increased from admission (98.54 mm) to discharge (110.72 mm) and 3-month follow-up (111.72 mm) in patients with heart failure (p<0.001).
