tachycardia (redirected fromatrial tachycardia) Thesaurus Medical Acronyms Encyclopedia tach·y·car·di·a (tăk′ĭ-kär′dē-ə) n. A rapid heart rate, especially one above 100 beats per minute in an adult. [tachy-+ Greekkardiā,heart; seecardia.] ...
Multifocal atrial tachycardia : a type of atrial arrhythmia characterized by rapid heart rate with at least 3 or more P wave morphologies. It is called multifocal since the signals arise from various zones within the atria other than the sinus node. Premature atrial contractions: common ectopic ...
Tachycardia cycle length was similar between septal AT and free-wall AT (367 卤 46 msec vs 366 卤 58 msec, P > 0.05). More patients with septal AT required isoproterenol to facilitate induction (44.9% vs 31.5%, P < 0.05). Septal AT was more sensitive to adenosine than free-wall AT ...
The patient’s heart rate was relatively fast, fluctuating in the range of 70 - 150 bpm, which frequently triggered the monitor’s “tachycardia” related alarm, and occasionally triggered the “extreme tachycardia” alarm with a heart rate exceeding 170....
Three patients with arrhythmias due to digitalis intoxication showed a significant reduction of ventricular rate in response to propranolol. One case of ventricular tachycardia and another of atrial tachycardia with block were converted to ... JRB Turner - 《American Journal of Cardiology》 被引量: ...
This should not be confused with the variable P waves of chaotic atrial tachycardia or with U waves, as mentioned earlier. The ventricular rate in patients with atrial fibrillation tends to be fast when it first occurs. The rate may range around 150 bpm. A clue to underlying conduction ...
AFSS scores range from a minimum of 0 to 35 points, with higher scores indicating greater AF symptom severity. Other prespecified secondary outcomes included the individual components of the primary outcome (AF, atrial flutter, and atrial tachycardia), repeat ablation, a composite outcome of atrial...
These tiered therapies range from providing anti-tachycardia pacing pulses or cardioversion energy for treating tachyarrhythmias to high energy shocks for treating atrial and/or ventricular fibrillation. To effectively deliver these treatments, the ICD must first detect that a tachyarrhythmia is occurring,...
