OBJECTIVE Study the prevalence of neurocardiogenic etiology in patients with unexplained syncope and ventricular premature beats, with right ventricle outflow tract morphology (RVOT) and no apparent structural cardiopathy. METHODS Ninety patients (66 women, mean age 40.2 +/- 16.95 years of age) with monomorphic premature beats originated at RVOT were evaluated prospectively. Fifty-four patien...

This case highlights the importance of considering a wide differential diagnosis in a young patient with chest pain and an abnormal ECG. Rarer causes of myocarditis such as GCM should be sought in patients who develop ventricular arrhythmias or high-grade heart block because the treatment is different and dramatically influences outcome. Our patient is the first reported case of GCM and a concu...
