Lown–Ganong–Levine syndrome (LGL) is a pre-excitation syndrome of the heart. Those with LGL syndrome have episodes of abnormal heart racing with a short PR interval and normal QRS complexes seen on their electrocardiogram when in a normal sinus rhythm.
Postural orthostatic tachycardia syndrome (POTS) is a condition characterized by an abnormally large increase in heart rate upon sitting up or standing. [1] POTS is a disorder of the autonomic nervous system that can lead to a variety of symptoms, [10] including lightheadedness, brain fog, blurred vision, weakness, fatigue, headaches, heart palpitations, exercise intolerance, nausea ...
Some patient portal applications enable patients to register and complete forms online, which can streamline visits to clinics and hospitals. Many portal applications also enable patients to request prescription refills online, order eyeglasses and contact lenses, access medical records, pay bills, review lab results, and schedule medical ...
Congenital heart problems e.g. pulmonary artery stenosis (common), Tetralogy of Fallot, overriding aorta, ventricular septal defect; and right ventricular hypertrophy. Liver (jaundice, pruritus, hepatosplenomegaly, acholia, xanthoma) Andersen–Tawil syndrome: This condition affects the QT interval (in blue) Antley–Bixler syndrome: Barth syndrome
The funny current is highly expressed in spontaneously active cardiac regions, such as the sinoatrial node (SAN, the natural pacemaker region), the atrioventricular node (AVN) and the Purkinje fibres of conduction tissue. The funny current is a mixed sodium–potassium current that activates upon hyperpolarization at voltages in the diastolic ...
The neurocardiac axis is the link to many problems regarding the physiological functions of the body. This includes cardiac ischemia, stroke, epilepsy, heart arrhythmias and cardiac myopathies. Many of these problems are due to the imbalance of the nervous system, resulting in symptoms that affect both the heart and the brain.
Cardiology Re-entry ventricular arrhythmia is a type of paroxysmal tachycardia occurring in the ventricle where the cause of the arrhythmia is due to the electric signal not completing the normal circuit, but rather an alternative circuit looping back upon itself. [ 1 ]
A patient with a paralysis is referred to an oncologist if the condition is caused by a cancer metastasis in the spinal cord; a treatment by a neurologist is a secondary consideration. Likewise, renal insufficiency is sometimes caused by heart problems, and the treatment is thus led by a cardiologist. In psychiatry, however, grouping mental ...
