2. Paroxysmal nocturnal dyspnoea - Wikipedia

   en.wikipedia.org/wiki/Paroxysmal_nocturnal_dyspnoea

   Since paroxysmal nocturnal dyspnea occurs mainly because of heart or lung problems, common risk factors include those that affect the function of the heart and lungs. Risk factors for cardiac diseases include high blood pressure, high cholesterol, diabetes, obesity, and a lifestyle lacking exercise and a healthy diet.

3. Supraventricular tachycardia - Wikipedia

   en.wikipedia.org/wiki/Supraventricular_tachycardia

   Atrial fibrillation: Red dots show atrial fibrillation activity. Atrial fibrillation meets the definition of SVT when associated with a ventricular response greater than 100 beats per minute. It is characterized as an "irregularly, irregular rhythm" both in its atrial and ventricular depolarizations and is distinguished by its fibrillatory ...

4. Palpitations - Wikipedia

   en.wikipedia.org/wiki/Palpitations

   A rapid, irregular rhythm might be due to atrial fibrillation, atrial flutter, or tachycardia with a variable block. [1] Supraventricular and ventricular tachycardias often cause sudden palpitations, beginning and ending rapidly. If someone can stop their palpitations with the Valsalva maneuver, it may indicate SVT. [1]

5. Ectopic beat - Wikipedia

   en.wikipedia.org/wiki/Ectopic_beat

   Ectopic beat is a disturbance of the cardiac rhythm frequently related to the electrical conduction system of the heart, in which beats arise from fibers or group of fibers outside the region in the heart muscle ordinarily responsible for impulse formation (i.e., the sinoatrial node).

7. Cardiac arrest - Wikipedia

   en.wikipedia.org/wiki/Cardiac_arrest

   Defibrillation cannot be applied to asystole and CPR must be initiated first in this case. A similar concept, cardioversion, utilizes the same defibrillation machine but is used for other rhythms such as atrial fibrillation and supraventricular tachycardia. In these rhythms, the machine is "synchronized" to the QRS complex to avoid shocking on ...

8. Alcohol use may cause atrial fibrillation, other heart problems

   Two recent studies in rodents suggest that binge drinking may cause atrial fibrillation, and that alcohol use may lead to heart problems in females undergoing estrogen replacement therapy.

9. Atrial tachycardia - Wikipedia

   en.wikipedia.org/wiki/Atrial_tachycardia

   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 of the heart, rather than from the sinoatrial node, the normal origin of the heart's electrical activity.
