The hexaxial reference system is a diagram that is used to determine the heart's electrical axis in the frontal plane.. In electrocardiography, left axis deviation (LAD) is a condition wherein the mean electrical axis of ventricular contraction of the heart lies in a frontal plane direction between −30° and −90°.
Atrial flutter was first identified as an independent medical condition in 1920 by the British physician Sir Thomas Lewis (1881–1945) and colleagues. [5] AFL is the second most common pathologic supraventricular tachycardia but occurs at a rate less than one-tenth of the most common supraventricular tachycardia (atrial fibrillation).
Anterior interosseous syndrome is a medical condition in which damage to the anterior interosseous nerve (AIN), a distal motor and sensory branch of the median nerve, classically with severe weakness of the pincer movement of the thumb and index finger, and can cause transient pain in the wrist (the terminal, sensory branch of the AIN innervates the bones of the carpal tunnel).
[1] [5] People with TIC may have symptoms associated with heart failure (e.g. shortness of breath or ankle swelling) and/or symptoms related to the tachycardia or arrhythmia (e.g. palpitations). [1] [2] Though atrial fibrillation is the most common cause of TIC, several tachycardias and arrhythmias have been associated with the disease. [5] [1]
Irregular "fluttering" suggests atrial fibrillation, atrial flutter, or tachycardia with variable block. [1] "pounding in the neck" or neck pulsations, often due to cannon A waves in the jugular vein. These occur when the right atrium contracts against a closed tricuspid valve. [6] Palpitations often come with other symptoms.
Cardiac symptoms of heart failure include chest pain/pressure and palpitations.Common noncardiac signs and symptoms of heart failure include loss of appetite, nausea, weight loss, bloating, fatigue, weakness, low urine output, waking up at night to urinate, and cerebral symptoms of varying severity, ranging from anxiety to memory impairment and confusion.
Symptoms: Pain, weakness, loss of muscle at the base of the thumb, swelling, paleness, bluish coloration [1] [2] Usual onset: 20 to 50 years of age [1] Types: Neurogenic, venous, arterial [1] Causes: Compression of the nerves, arteries, or veins in the superior thoracic aperture (thoracic outlet), the passageway from the lower neck to the ...
Those affected by arrhythmogenic cardiomyopathy may not have any symptoms at all despite having significant abnormalities in the structure of their hearts. [6] If symptoms do occur, the initial presentation is often due to abnormal heart rhythms (arrhythmias) which in arrhythmogenic cardiomyopathy may take the form of palpitations, or blackouts. [7]
