Abstract

We are presenting a 79-year-old woman with congestive heart failure (CHF) and marked peripheral edema, who responded to medical management by losing 19.7% of her weight. The patient was studied with daily weights, 12-lead electrocardiograms (ECGs), and body electrical resistance/reactance/impedance (R/R/I) measurements via electrodes applied on her hand and foot. In the process she showed a gradual increase in the QRS complexes in her daily ECGs pari passu with the weight loss, leading to a 27.4% increase in the sums of the QRS complexes from the 12 ECG leads ( summation operator SQRS). In addition the patient revealed excellent correlations between weights and summation operator SQRS (r = -.91, P =.013), weights and resistance (r = -.95, P =.004), reactance (r = -.86, P =.029), and impedance (r = -.95, P =.004). Other ECG sets including fewer leads were also employed and correlated with weights and the body electrical properties. It is concluded that loss of peripheral edema in patients with CHF is associated with augmentation of body R/R/I leading to augmented ECG QRS complexes. These findings link etiologically changes of ECG potentials to alteration of body electrical properties, and suggest that serial ECGs could be used i...Continue Reading

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
