Medtronic paths associated with this specificity

Sixty-four year old woman with a history of myocardial infarction and a preserved ejection fraction (left ventricular ejection fraction: 58%); three episodes of abrupt syncope without clear context; the ECG in sinus rhythm shows an incomplete right bundle branch block associated with a sequel of inferior myocardial infarction; complementary exams, including an electrophysiological study with programmed ventricular pacing are negative; immediately before installation of the

A 62-year-old man presented with recurrent, malignant, vagal syncope, including a few episodes complicated by traumas. A tilt-table test elicited a mixed vasodilatory and bradycardia response. An ILR (Reveal DX) was implanted in hope of observing a spontaneous episode

A 48-year-old man presented with a several-year history of multiple syncopal events occurring in circumstances of enhanced vagal activity, such as after meals, or in church. The episodes were associated with prodromes, including perspiration and a sensation of warmth. He presented after 2 recent episodes of sudden loss of consciousness without prodrome, the latter complicated by a fall and facial trauma.

An 81-year-old woman presented with 2 sudden episodes of syncope without trauma. The ECG reveals normal PR and QRS intervals at 190 and 95 ms, respectively. A 48-h ambulatory ECG was normal. Electrophysiological studies revealed no intra or infra-Hisian block. A Reveal DX was implanted.

A 63-year-old man suffering from ischemic cardiomyopathy, old anterior myocardial infarction with a 48% left ventricular ejection fraction, non-specific bundle branch block and 120-ms QRS duration underwent negative electrophysiological studies and programmed ventricular stimulation after a sudden episode of syncope. A Reveal DX was implanted.

A 14-year-old adolescent without personal or family medical history presented after 4 episodes of syncope. Except for early repolarization in the inferior ECG leads and ventricular extrasystoles originating from the left ventricular outflow tract, all investigations were negative.

A 47-year-old severely depressed man without heart disease complained of multiple atypical episodes of syncope without prodrome, triggering event or trauma. ECG and imaging studies were unremarkable. Under pressure from his relatives, a Reveal DX was implanted and the patient was followed remotely by home monitoring.

A 66-year-old man underwent implantation of a Reveal XT for recurrent syncope without apparent precipitating cause. An ECG and echocardiogram were normal.

A 74-year-old man with a history of inferior myocardial infarction and 45% left ventricular ejection fraction underwent implantation of a Reveal DX for the diagnosis of syncope preceded by palpitation. The ECG showed complete right bundle branch block and electrophysiological studies revealed a HV interval at 63 ms. Programmed ventricular pacing was unremarkable.

A 54-year old man suffering from ischemic cardiomyopathy with a left ventricular ejection fraction of 56% presented after 2 syncopal episodes. After undergoing negative electrophysiological studies and programmed ventricular stimulation, the patient underwent implantation of a Reveal DX.

A 44-year-old man presenting with hypertrophic cardiomyopathy and a history of first transient stroke 2 years earlier, was hospitalized after a 2nd ischemic attack associated with a transient motor deficit of the left side of the body. Computed tomography scan, magnetic resonance imaging study, transesophageal echocardiogram, ECG, 48-h ambulatory ECG and carotid Doppler were normal.

A Reveal XT was implanted for monitoring of atrial arrhythmias.

A 67-year-old man complained of recurrent syncope with perception of palpitation before losing consciousness. He has a history of treated systemic hypertension and concentric LV hypertrophy. The 12-lead ECG showed right bundle branch block and electrophysiological studies were negative. A Reveal DX was implanted.

A 62-year-old woman suffered a possible episode of syncope while driving, complicated by a car accident. All diagnostic tests were normal, including an echocardiogram and an ECG, which showed a narrow QRS. Because of the seriousness and consequences of the accident, a Reveal DX was implanted after this first and only episode.
