Cardiac asthma is the medical condition of intermittent wheezing, coughing, and shortness of breath that is associated with underlying congestive heart failure (CHF). [1] Symptoms of cardiac asthma are related to the heart's inability to effectively and efficiently pump blood in a CHF patient. [2] This can lead to accumulation of fluid in and ...
Paroxysmal nocturnal dyspnea or paroxysmal nocturnal dyspnoea ( PND) is an attack of severe shortness of breath and coughing that generally occurs at night. [1] It usually awakens the person from sleep, and may be quite frightening. [2] PND, as well as simple orthopnea, may be relieved by sitting upright at the side of the bed with legs ...
Multifocal (or multiform) atrial tachycardia (MAT) is an abnormal heart rhythm, [2] specifically a type of supraventricular tachycardia, that is particularly common in older people and is associated with exacerbations of chronic obstructive pulmonary disease (COPD). Normally, the heart rate is controlled by a cluster of cells called the ...
Paroxysmal attack. Paroxysmal attacks or paroxysms (from Greek παροξυσμός) are a sudden recurrence or intensification of symptoms, such as a spasm or seizure. [1] These short, frequent symptoms can be observed in various clinical conditions. They are usually associated with multiple sclerosis or pertussis, but they may also be ...
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 ...
Junctional tachycardia is a form of supraventricular tachycardia characterized by involvement of the AV node. [1] It can be contrasted to atrial tachycardia. It is a tachycardia associated with the generation of impulses in a focus in the region of the atrioventricular node due to an A-V disassociation. [2]
2.3 per 1000 people [5] Paroxysmal supraventricular tachycardia ( PSVT) is a type of supraventricular tachycardia, named for its intermittent episodes of abrupt onset and termination. [3] [6] Often people have no symptoms. [1] Otherwise symptoms may include palpitations, feeling lightheaded, sweating, shortness of breath, and chest pain.
Atrial tachycardia is a type of heart rhythm problem in which the heart 's electrical impulse comes from an ectopic pacemaker (that is, an abnormally located cardiac pacemaker) in the upper chambers ( atria) of the heart, rather than from the sinoatrial node, the normal origin of the heart's electrical activity .
