The various forms of Sinus Arrhythmia are:

It is possible for sinus arrhythmia to strike at any age. Although, the condition is more common in the elderly striking most people after reaching the age of seventy. Sinus arrhythmia does not usually describe only one kind of heart rhythm difficulty, but several difficulties concerning various kinds of arrhythmias.

Our hearts naturally have a pacemaker which keeps it beating. The heart's pacemaker is found in the heart chamber on the upper right and is known as the sinus node. The sinus node produces electrical impulses continually throughout our lifetime. If the pattern is disrupted, the natural rhythm of our heartbeat can become erratic.

When a person is suffering with sinus arrhythmia, variations of heartbeats happen. Heartbeats can go from one abnormal pace to another. The heart may beat very slowly one minute, then suddenly pick up the pace, and possibly go into an extended pause mode before attempting to correct the problem.

* Tachycardia-bradycardia is a dangerous form of which forming a blood clot is most likely to occur. With this condition, the heart constantly beats between rhythms that are entirely too fast or extremely slow.

* Sinoatrial block problem is a type of sinus arrhythmia where electrical impulses in the sinus node are received much too slowly.

* With the condition known as Sinus Arrest, there are far too many pauses in heartbeats as though the heart rhythm may slowly come to a complete stop.

Early symptoms of sinus arrhythmias may probably go unnoticed. If you experience signs of erratic heartbeat rhythm disturbances, they are usually not consistent. However, over time as the condition progresses, you could experience some of the following warning signs:

* Dizziness
* Fainting
* Shortness of breath
* Memory Loss
* Angina
* Insomnia
* Tiredness
* Heart palpitations

If you are feeling ill and having any of these symptoms, visit your doctor. In diagnosing sinus arrhythmia the doctor will perform the following medical tests:

* Listen carefully with a stethoscope to your heartbeat for several minutes.

* An EKG which is an electrocardiogram will be done to check your heart patterns.

* A step further from an EKG for diagnosis, your physician or cardiologist may order a holter monitor test. You wear at all times while performing the testing. The monitor will record your heart rhythm patterns continually. The monitor is typically worn for up to 48 hours so that it gives an accurate assessment of rhythm patterns. Along with the monitor, you will keep a journal recording of anytime you feel strange or your heartbeat feels erratic. The physicians will analyze the data and compare the times when you may feel ill to the monitored heart patterns.

* An echo-cardiogram will also generally be done. This gives more details on the heart chambers as to their performance. The echo-cardiogram will clearly show any defects such as enlargement of the heart.

The danger of sinus arrhythmia is the formation of blood clots which can lead to strokes. This is why it is imperative for the doctor to prescribe medication to regulate your heartbeat or you may need to resort to a pacemaker.

Beta blockers along with a calcium channel blocker may help sinus arrhythmia. Both of these drugs help regulate the heart and stabilize blood pressure. However, if the drugs do not benefit you, chances are you may need to receive a pacemaker.
