Respiration was continuously monitored through a permanent tracheostomy, and the electrocardiogram and blood pressure were also monitored. We examined the hypothesis that respiratory sinus arrhythmia (RSA) is primarily a central phenomenon and thus that RSA is directly correlated with respiratory controller output. RSA was measured in nine anesthetized dogs, first during spontaneous breathing (SB) and then during constant flow ventilation (CFV), a technique whereby phasic chest wall movements and thoracic pressure swings are Hearing of heart arrhythmia in dogs for the initial time may scare pretty much any pet owner. Who would not be worried as they learn that there’s something wrong with their dog’s heart? With that being said, things typically seem to become a lot less frightening when we try to understand them. The same thing goes for heart arrhythmia in dogs.

Sinus arrhythmia in dogs

Respiration was continuously monitored through a permanent tracheostomy, and the electrocardiogram and blood pressure were also monitored. However, some dogs with paroxysmal SVT are in sinus rhythm at the time of presentation. Obtaining a 6- to 12-lead surface ECG is the initial step in identifying the arrhythmia. Further characterization of the SVT is obtained by ambulatory 24-hour ECG recordings (Holter monitoring). Sinus arrhythmia is a normal physiologic arrhythmia that occurs at slow resting heart rates and is associated with variation in the rate of discharge from the SA node associated with variation in the intensity of vagal stimulation. Lead I-III in a dog showing an underlying sinus rhythm with two, ventricular couplets.

Figure 4C Six-lead ECG in a dog with an auscultated arrhythmia. There is sinus rhythm with multiple polymorphic VPCs (arrow), a single APC (arrow), and a fusion beat (circled), which results from a sinus beat and a VPC occurring at the same time and causing fusion of the two complexes on the ECG, with a PR interval similar to that of the other In relaxed dogs, the heart rate quickens during inhalation and slows when the dog exhales and pauses between breaths. By comparison, a cat’s heartbeat remains steady.

The heart may beat too fast, too slow, or it may skip beats. An occasional irregular heart beat may not cause any other health problems. Sinus arrhythmia is a normal physiologic arrhythmia that occurs at slow resting heart rates and is associated with variation in the rate of discharge from the SA node associated with variation in the intensity of vagal stimulation. Sinus arrhythmia occurs when the dog’s heart rate accelerates during inhalation and slows during exhalation. Causes Heartbeat arrhythmia may be caused by genetic factors, infections, breed predisposition, congenital heart abnormalities, gastrointestinal disease, brachycephalic conformation, digoxin therapy, heart disease, toxins, dehydration or electrolyte imbalance, blood loss, stress, and 2020-02-18 The word arrhythmia refers to an irregular heartbeat. Dogs and cats with a sinus arrhythmia have times when their heart beats faster and times when it beats slower. In contrast to a normal sinus rhythm, there is a variation in the time between the heartbeats.
