Hey mate....
Here's ur answer :
»» A Sinus arrhythmia is an irregular heartbeat that's either too fast or too slow. One type of sinus arrhythmia, called respiratory sinus arrhythmia, is when the heartbeat changes pace when you inhale and exhale. In other words, your hearbeat cycles with your breath. When you breath, in your heart rate increases. When you exhale, it falls.
Symptoms :
- Palpitations
- Slow heart rate
- Shortness of breath
Causes :
- Any interruption to the electrical impulses that cause the heart to contract can result in arrhythmia
- For a person with a healthy heart, they should have a heart rate between 60-100 beats per minute when resting
- The more fit a person is, lower their resting heart beat
It can caused by :
- alcohol abuse
- diabetes
- drug abuse
- excessive coffee consumption
- heart disease like congestive heart failure
- hypertension (high blood pressure)

Hey mate............... here's your answer
An irregular heartbeat is called an arrhythmia. A sinus arrhythmia is an irregular heartbeat that’s either too fast or too slow. One type of sinus arrhythmia, called respiratory sinus arrhythmia, is when the heartbeat changes pace when you inhale and exhale. In other words, your heartbeat cycles with your breath. When you breathe in, your heart rate increases. When you exhale, it falls.
This condition is benign. It’s a naturally occurring heartbeat variation, and it doesn’t mean you have a serious heart condition. In fact, this condition is common in young, healthy adults and children.
A respiratory sinus arrhythmia can occur in older individuals, but in these cases, it’s often associated with heart disease or another heart condition.
Sometimes, sinus arrhythmia occurs with another condition called sinus bradycardia. Bradycardia, or a slow heartbeat, is diagnosed when your heart’s natural rhythm is below 60 beats per minute. If the low heart rate produces lengthy pauses between beats, you may have sinus bradycardia with sinus arrhythmia. These pauses can be commonTrusted Source while you sleep.
Another type of sinus arrhythmia occurs when the heart beats too fast. This is called sinus tachycardia. It refers to heart rates above 100 beats per minute. Sinus tachycardia is usually a result of another condition, such as stress, fever, pain, exercise, or medications. If the rapid heart rate doesn’t resolve quickly, your doctor will treat the underlying problem.
In a young and otherwise healthy person, these conditions are not serious or problematic. Some people with a slow or fast heartbeat might experience symptoms like lightheadedness or shortness of breath, but others may never experience symptoms at all.What are the symptoms?
People with a sinus arrhythmia don’t experience any cardiovascular symptoms. In fact, you may never experience symptoms of any kind, and the condition may never be diagnosed.
If you know how to detect your pulse, you might feel a slight change in your pulse rate as you breathe in and exhale. However, the differences may be so slight that only a machine can detect the variations.
If you experience heart palpitations or feel like your heart is skipping a beat, talk with your doctor. Heart palpitations are rarely serious, and they can happen from time to time. Still, they may be worrisome, and checking with your doctor can help you rest assured you don’t have any underlying heart issues.
What causes sinus arrhythmia?
It’s not clear what causes people to develop a sinus arrhythmia. Researchers suspect that a connection between the heart, lungs, and vascular system may play a role.
In older individuals, a sinus arrhythmia can occur as a result of heart disease or another heart condition. Damage to the sinus node can prevent the electrical signals from leaving the node and producing a steady, normal heartbeat. In these cases, the sinus arrhythmia is the result of damage to the heart, and it’s likely to show up after the heart condition develops.
