The presence of supraventricular tachycardia is the leading cause of inappropriate shock in ICD recipients, and it can be a significant cause of morbidity, psychological distress and worsened clinical outcome. Modern pacing and ICD systems offer a number of discriminators that are integrated into algorithms to differentiate sustained ventricular tachycardia from supraventricular tachycardia. These algorithms can be adapted and optimised for each individual patient to ensure that only those arrhythmias that need treatment through the use of an ICD, are actually treated. This review summarises the single- and dual-chamber discriminators that can be used in the detection and classification of tachyarrhythmias.

Cardiac calcified amorphous tumors are rare non-neoplastic intracavitary masses with unknown cause. A 60-year-old man presented with sustained ventricular tachycardia. Transthoracic echocardiography and contrast-enhanced angio-computed tomography demonstrated an expanding 73 × 40 mm sized calcified mass in the left ventricle. He underwent successful total removal of the mass and cryo-ablation at the normal myocardial border. Histopathological examination confirmed a diagnosis of cardiac calcified amorphous tumors. The postoperative course was uneventful, without ventricular tachycardia recurrence. To our knowledge, this is the first reported case of confirmed cardiac calcified amorphous tumors causing ventricular tachycardia and treated by surgical resection combined with cryo-ablation.
