Hypertrophic Cardiomyopathy
Fig. 11.1 12-lead ECG The initial EKG showed sinus rhythm at 58 bpm, normal atrioventricular conduction (PR interval 160 s), normal QRS duration (0.08 s), absent Q wave, and horizontal…
Catecholaminergic Polymorphic Ventricular Tachycardia: A Challenging Case of “Epilepsy”
Fig. 26.1 Onset of polymorphic VT symptomatic for syncope, converted to sinus rhythm after cardiopulmonary resuscitation Fig. 26.2 Restoration of sinus rhythm with frequent monomorphic PVCs Clinical Course and Therapeutic…
Brugada Syndrome
Fig. 24.1 ECG performed at hospital admission Sinus rhythm, heart rate 95 bpm, normal atrioventricular conduction (PQ 150 ms), cardiac electrical axis +60°, and coved-type ST-segment elevation about 4 mm,…
Left Ventricular Non-compaction Cardiomyopathy
Fig. 13.1 Routine ECG. Notice the normal sinus rhythm without abnormalities in conduction or repolarization Chest X-Ray A chest x-ray was performed too (Fig. 13.2): cardiac shadow was slightly enlarged…
Cardiac Amyloidosis
Fig. 12.1 Rest EKG performed in hospital Conclusions: sinus rhythm, normal atrioventricular conduction, counterclockwise rotation on horizontal axis, low voltages on limb leads, and diffuse nonspecific alterations in repolarization Routine…

Mitral Regurgitation
Fig. 16.1 Echocardiography, four-chamber view. From left to right: two-dimensional imaging shows thickened mitral leaflet with posterior leaflet prolapse (arrow). Color Doppler shows severe eccentric mitral regurgitation swirling toward interatrial…
Cardiac Resynchronization Therapy and Possible Dysfunctions
Fig. 10.1 12-lead ECG in atrial fibrillation with biventricular pacing Although the patient’s heart failure symptoms improved from NYHA classes III to II and biventricular pacing achieved a success rate…
