Sinus rhythm means

Wikipedia Rate this definition: 0.0 / 0 votes • Sinus rhythm A sinus rhythm is any cardiac rhythm in which depolarisation of the cardiac muscle begins at the sinus node. It is characterised by the presence of correctly oriented P waves on the electrocardiogram (ECG). Sinus rhythm is necessary, but not sufficient, for normal electrical activity within the heart.The term normal sinus rhythm (NSR) is sometimes used to denote a specific type of sinus rhythm where all other measurements on the ECG also fall within designated normal limits, giving rise to the characteristic appearance of the ECG when the electrical conduction system of the heart is functioning normally; however, other sinus rhythms can be entirely normal in particular patient groups and clinical contexts, so the term is sometimes considered a misnomer and its use is sometimes discouraged. Other types of sinus rhythm that can be normal include sinus tachycardia, sinus bradycardia, and sinus arrhythmia. Sinus rhythms may be present together with various other cardiac arrhythmias on the same ECG.

I have had a b/ventricular p/m since Oct 2005,it needed replacing in Jan 2015 due to battery nearing going flat,in Melb they put an ordinary p/m in because he was the only one in S/East Aust registered to remove the leads,after 18 months it was not successful,my E/F although was static at 58%,fell to 38% in the 18 months,in Hobart they put a B/V back in and I have been a lot better to the point that today I am back into Sinus Rhythm,for how long I don't know,but have probably been back in S/R for 2/3 months.I don't know what my E/F is today because I haven't had an Echo Cardiagram. Basically you have a normal ECG reading according to the machine. Sinus rhythm ( The "otherwise normal" is boilerplate by the machine. As you can see by [rhythm message here] otherwise normal ECG". Better programming would be to omit the "otherwise" when the sinus rhythm is normal. Now, realize that the machine is simply applying preformatted parameters, and that when it says normal, it just means that your readings fit into what it has defined as normal. It is possible that there is some small thing that doesn't look out of place to the machine but would to a trained cardiologist. I don't say that to alarm you, but just to show you how the machine interprets it. Basically I agree with JohnP. The "otherwise normal ecg" is an unfortunate phrase. Sinus rhythm is the normal rhythm of the heart. So the machine should interpret as: Normal ECG. Rhythm:Sinus Heart Rate : PR interval: etc etc. By saying...

What Does Normal Sinus Rhythm (NSR) Mean? Normal sinus rhythm (NSR) is a physiological function of the heart rate that begins at the sinus node, the locus of bioelectric activity that stimulates the chambers called the atria (top) and its corresponding ventricles (bottom) to pump blood through the body. In medicine, normal sinus rhythm serves as a criterion in assessing the relative health of the heart muscle where baseline metrics range between 60 and 99 beats per minute. WorkplaceTesting Explains Normal Sinus Rhythm (NSR) Normal sinus rhythm can fluctuate to the extent that the electrical impulses are proportionate to atrial and ventricular contractions that quicken or slow heart rate. An irregular heartbeat can reflect variables including sustained exertion (i.e., exercise), homeostatic response (i.e., fever), pathological condition (i.e., anemia) and environmental circumstances related to stress. Sinus rhythm abnormalities fall into two categories including bradycardia (slow heart rate) and tachycardia (fast heart rate). Sinus rhythm deviations can also indicate an otherwise normal heart rate, for example, physical exercise induces sinus tachycardia to ensue. As a result, maximal cardiac output helps expedite the distribution of oxygenated blood to specific muscles in the body, offsetting fatigue. Conversely, bradycardia is a biological consequence of normal sleep patterns as heart rate decreases, suspending motor activity. Sleep disorders can influence heart rate by d...

Heart rate variability is where the amount of time between your heartbeats fluctuates slightly. Even though these fluctuations are undetectable except with specialized devices, they can still indicate current or future health problems, including heart conditions and mental health issues like anxiety and depression. Overview What is heart rate variability? Heart rate variability is where the amount of time between your These fluctuations are undetectable except with specialized devices. While heart rate variability may be present in healthy individuals, it can still indicate the presence of health problems, including heart conditions and mental health issues like anxiety and depression. Is heart rate variability like an arrhythmia? Heart rate variability is a normal occurrence, and it isn’t an The normal beating of your heart is called “sinus rhythm.” When your heart is beating normally but the variability between heartbeats is greater than 0.12 seconds, this is called “sinus arrhythmia.” Heart rate variability can sometimes meet the criteria for sinus arrhythmia. Sinus arrhythmia is usually due to breathing (this is called respiratory sinus arrhythmia), which is part of a normal reflex of your heart and circulatory system. However, when sinus arrhythmia isn’t caused by breathing, it may be a sign of another heart problem that does need assessment by a healthcare provider. How does heart rate variability work? Your heart beats at a specific rate at all times. That rate chan...

What is a Sinus Rhythm? This page provides an introduction to sinus rhythms and links to our EKG interpretation courses and drills. A normal sinus rhythm refers to both a normal heart rate and rhythm. Normal heart rates are from 60 to 100 beats per minute. The shape of the electrocardiogram (EKG) tracing will exhibit certain key attributes to be considered normal, as discussed below. With normal sinus rhythms, the heart beat's electrical impulse originates in the sinoatrial node (SA). The P waves are upright and appear before each QRS and have the same shape. The intervals between the P waves are regular, although some variations can occur with respiration. Sinus rhythms are classified as: • Normal Sinus Rhythm • Sinoatrial Block • Sinus Pause • Sinus Arrhythmia • Sinus Bradycardia • Sinus Tachycardia Sinus Pause Sinus pause includes sinus arrest and sinus exit block. Sinus arrest is caused by failure of the SA node to create an impulse. An interruption in R-R regularity can be observed. With sinus exit block the SA node generates an impulse but it is blocked before being transmitted through the atria. R-R regularity continues with the beats that follow the missed beat. Depressed ST segments can also be observed. Learning Objectives At the conclusion of this training module the reader will be able to: • Recall and apply the 5-steps of heart rhythm interpretation • Recognize the difference between regular and irregular rhythms • Recall the normal range for PR interval and Q...

Other types of sinus rhythm that can be normal include Characteristics [ ] In humans, for an ECG to be described as showing a sinus rhythm, the shape of the P wave in each of the 12 standard • always positive in lead I, lead II, and aVF • always negative in lead aVR • any of biphasic (-/+), positive or negative in lead aVL • positive in all chest leads, except for V1 which may be biphasic (+/-) If the P waves do not meet these criteria, they must be originating from an abnormal site elsewhere in the atria and not from the sinus node; the ECG cannot, therefore, be classed as showing a sinus rhythm. In general, each P wave in a sinus rhythm is followed by a QRS complex, and the sinus rhythm therefore gives rise to the whole heart's depolarization. Exceptions to this include Characteristics of normal sinus rhythm [ ] By convention, the term "normal sinus rhythm" is taken to imply that not only are the P waves (reflecting activity of the sinus node itself) normal in morphology but that all other ECG measurements are also normal. • Normal heart rate (classically 60 to 100 beats per minute for an adult). • Regular rhythm, with less than 0.16-second variation in the shortest and longest durations between successive P waves • The sinus node should pace the heart – therefore, P waves must be round, all the same shape, and present before every • Normal P wave axis (0 to +75 degrees) • Normal • QRS complex positive in leads I, II, References [ ] • Hampton, John R (2013).
