What Is Sinus Bradycardia
Slow heart rate: Generally a heart rate less than 50 beats per minute coming from the heart's natural pacemaker is considered sinus bradycardia. It is not necessarily abnormal as well conditioned athletes often have low heart rates. Some medications such as beta blockers slow the heart rate to this level. ...Read moreSee 1 more doctor answer
In anatomy, a sinus is a cavity within a bone or other tissue. Most commonly found in the bones of the face and connecting with the nasal cavities. Sinus (anatomy), description of the general term paranasal sinuses, air cavities in the cranial bones, especially those near the nose, including: the maxillary sinuses, also called the maxillary antra and the largest of the ...Read more
Normal: Sinus arrhythmia refers to a prominent, but normal, variation in heart rate. The heart beat begins in the sinus node. The sinus node is regulated by the autonomic nervous system. The system may react quickly enough to cause more noticeable changes in heart rate. This variation is usually more prominent in younger individuals. ...Read moreSee 1 more doctor answer
ECG findings: "Sinus bradycardia" means the HR is slower than expected but otherwise normal by ECG findings. "PRWP" stands for "poor R wave progression" - it's an ECG finding that is relatively non-specific but requires interpretation with respect to your cardiac risk factors otherwise. If you are at elevated cardiac risk, then further testing would be recommended, such as stress testing or angiogram. ...Read more
Fast heart rate: Tachycardia means fast heart beat. Sinus node is the structure where normally heart rhythm and beat is originated, and it naturally responds to stimuli when the heart needs to beat faster. Inappropriate sinus tachycardia is when the heart is beating fast, when it shouldn't. ...Read more
Good question!: The answer is basically inflammation but what does that mean? It means that when our nasal passages are exposed to allergens, viruses, bacteria or even environmental changes (weather, altitude), the blood vessels dilate and this alone can cause mild "congestion." With infection or allergies, cells from the immune system are recruited to the area and bring water/fluid to the nasal tissues. ...Read moreSee 1 more doctor answer
Sinus rhythm: Sinus rhythm is the normal rhythm of the heart. It is produced by depolarization of cells in the 'sinus node' of the right atrium. The signal goes from there around the heart. It first depolarizes the atria and causes P wave and the passes into the ventricles and causes the QRS and T waves. This usually happens at a rate of 60-100 beats a minute. ...Read more
See below: Sinus tachy with artifact is a normal but fast rhythm (>100) with externally caused variations in the appearance of the tracing caused by body movement, poor electrode contact or external electrical interference. Sin. tachycardia with PVC is normal but fast rhythm (rhythm >100), & a premature ventricular contraction (PVC), which is an abnormal early heart beat originating in one of the ventricles. ...Read more
No: Sinus bradycardia may just mean that your heart rate is slightly below the calculated and established "average hr" for the population. Now, if your hr is so low that it is causing symptoms, is not able to maintain adequate blood pressure and / or does not rise with increasing activity, then it is abnormal and you need to be evaluated. ...Read moreSee 2 more doctor answers
See below: Normal heart rhythm arises in specialized cells within the right atrium called the sinus node and then is propagated over specialized conducting tissue into both ventricles. When an irritable focus in a ventricle begins firing independently repeatedly or in a repetitive loop, initiating it's own renegade rhythm at a rapid rate, it's called ventricular (where it starts) tachycardia (rate >100). ...Read moreSee 1 more doctor answer
Supernormal rhythm: Sinus tachyarrhymia is a faster than normal rate with normal rhythm through the normal conduction pathways, meaning that there is no abnormal electrical conduction abnormality.The treatment is to treat the underlying cause. Frequent causes include fever, sepsis, respiratory difficulties from COPD or pulmonary embolism, sepsis, pain, psychological stress, acute heart failure, or myocardial ischemia. ...Read more
Slow heart rate, also called bradycardia, is defined as a resting heart rate (pulse) less than 60 beats per minute. Having a heart rate less than 60 is not necessarily abnormal. In fact, people in good cardiovascular shape have a low heart rate. People with certain heart conditions may take medications which lower the heart rate as one of ...Read more
