Electrocardiography of the failing heart.
Structural heart disease, electrical instability, and increased sympathetic activity can generate a number of specific and nonspecific ECG changes and arrhythmias in patients with congestive heart failure (CHF). This review describes direct alterations of the P-QRS-T complex and ECG-derived parameters in CHF, together with the significance of cardiac arrhythmias, markers of atrial and ventricular electrical instability, and the parameters of sympathetic nervous system activity.
