He observed that those sick with anxiety simmered for long periods, then suddenly the "foul fiend of fear" caused them to turn "red, pale, tremble, sweat, it makes sudden cold and heat come over the body, palpitation of the heart, syncope, etc".
The majority of adults with significant congenital cardiac disease present to the Emergency Department with symptoms related to cardiac arrhythmias, congestive heart failure, syncope, aortic dissection, endocarditis and pulmonary hypertension [3].
Following an intraperitoneal injection of a low (100 µg/kg) or high dose (10 mg/kg) of ouabain, or 2 mg/kg epinephrine conscious mice were monitored for heart rate, syncope, or death.
The following major events were considered: sustained ventricular tachycardia (VT), ventricular fibrillation (VF), cardiac arrest, heart failure, syncope, and chest pain.
Patients who, in the opinion of the investigator, have a medical condition that would preclude them from participating in the study, for example, chronic heart failure, syncope within the past year, significant valvular heart disease, that is, severe aortic and mitral stenosis, or symptomatic orthostatic hypotension within the last year.
In cardiology, placebos influence disability, syncope, heart failure, atrial fibrillation, angina, and survival.
However, few reports have mentioned heart failure-induced syncope in patients with giant hiatal hernias [3 10].
Patients with AS can present with different symptoms depending on the severity of stenosis ranging from chest pain, syncope, heart failure and/or sudden cardiac death.
Inclusion criteria were adults over 18 years old and any patients that had a cardiology performed echocardiography study for angina, syncope, heart failure symptoms or murmur.
MEASUREMENTS: Hospitalizations for myocardial infarction (MI), heart failure, and syncope or atrioventricular block in both cohorts; fatal or nonfatal MI and cardiac death in the Danish cohort; and all-cause mortality in sensitivity analyses.
The study population excluded patients with a history of cerebrovascular, cardiovascular, or atherosclerotic disease (including carotid artery disease, heart arrhythmias, or syncope) or any significant neurological or systemic disorder and patients with an implanted electrical device.
