Heart Failure Types — main categories?
Systolic (HFrEF) and diastolic (HFpEF) types.
Heart Failure — definition?
Inadequate blood pumping, causes symptoms like dyspnea, edema.
ECG Waveform Components — key parts?
P wave, QRS complex, T wave.
Systolic HF — EF?
Less than 40% ejection fraction.
ECG Abnormalities in HF — common findings?
Arrhythmias, bundle branch blocks, ischemic changes.
Diastolic HF — EF?
More than 50% ejection fraction.
HFrEF — characteristic?
Reduced EF, impaired ventricular contraction.
HFpEF — cause?
Impaired ventricular relaxation and filling.
Left-sided Heart Failure — symptoms?
Pulmonary congestion, respiratory symptoms.
Right-sided Heart Failure — symptoms?
Systemic congestion, peripheral edema.
