What is dysrhythmia? What are the Symptoms of Dysrhythmia? What to do for tachycardia?

Dysrhythmia, Tachydysrhythmias, Triggered Tachycardias


  • Out of the normal beat pattern (rhythm) of the heart
    all the irregularities in a familiar term
    arrhythmia, or more aptly dysrhythmia
  • Arrhythmia, impulse formation in the heart and
    in the transmission of the alert or both
    arise as a result of disorders.


Depending on the change in cardiac output;

  • Palpitation
  • Dizziness
  • Syncope
  • Chest pain
  • Temporary dizziness
  • Exercise intolerance
  • Heart failure

Tachydisrhythmias, Increased automaticity:

  • Increased automaticity
  • Re-entry
  • Trigger

Normal or ectopic focus
increased automaticity

  • Pacemaker of a focus other than the sinus node
  • activity and this focus
  • take on the role of a pacemaker

Reentry, Triggered Tachycardia, Tachydysrhythmias, Dysrhythmias with Narrow QRS, Sinus tachycardia

Reentry in normal or accessory way
It develops depending on the phenomenon.

In one of two separate transmission arms; Transmission delay, Unidirectional block

  • Increased calcium input for the cell
  • Myocardial infarction
  • Digital toxicity
  • Ectopic atrial rhythms
  • Nodal tachycardias
  • Torsades de Pointes

What is tachycardia?

One of the most common rhythm disorders is tachycardia. Tachycardia is when the heart beats more than 100 times a minute. One of its most prominent features is palpitations. In cases where the heart works very fast, it does not faint, it can also be observed as a drop in blood pressure or shortness of breath.

Methods such as MRI or ECG are applied to patients with palpitations. The palpitations of tachycardia patients are usually short-lived, so their heart rhythms may return to normal until they go to the nearest healthcare facility. For such patients, further examinations are required.

Ventricular Tachycardia

Ventricular tachycardia is a rapid pulse in the ventricular chambers of the heart. Ventricles are the main pumps that keep blood circulating throughout the body. Health an adult heart is 60 to 100 beats per minute. In the case of ventricular tachycardia, the heart rate can reach 200 to 250 beats per minute, as a result of the heart beating so fast, the ventricles do not fill the ventricles with enough blood, which can cause serious health problems.

Supraventricular Tachycardia

Supraventricular tachycardia is one of the most common types of tachycardia in childhood. It can usually manifest itself in infancy with symptoms such as fatigue, restlessness and not breastfeeding. Children have complaints such as palpitations, chest pain and, rarely, fainting. Children with supraventricular tachycardia have normal heart rates and anomalies such as palpitations are rarely observed. If supraventricular tachycardia is detected in a child, drug treatment should be started as soon as possible.

Sinus Tachycardia

Sinus tachycardia is called the heart rhythm beats 100 or more per minute without disrupting the heart rhythm as a result of physical activity, trauma, stress or such events. Although sinus tachycardia that develops due to physical activities is normal, a doctor must be consulted.

What Should Be a Normal Heart Rate?

Although normal heart rate values ​​vary from person to person, the normal pulse rate of an adult is generally accepted in the range of 60 to 100. As long as the pulse does not fall below 50, a low pulse rate indicates that people are healthier.

Heart Rate After Sport

People who do sports can usually have a heart rate of 50 or slightly below during rest. The lower the heart rate at rest, the better for people. During sports, the pulse rate should be at most 125. If this number rises to 125 and above, the person can be life-threatening. Therefore, you should definitely measure your average heart rate during and after sports, and if an anomaly is found, a doctor should be consulted as soon as possible.

Heart Rate in Babies and Children

Babies and children have a different heart rate than adults. While the average pulse rate is 100 to 125 in babies, it is considered normal between 80 and 100 in children.

Pulse in women

The average heart rate in women is between 70 and 90 as normal.

Heart Rate in Men

Although a normal pulse rate is normally observed at values ​​between 60 and 100, the average ideal heart rate for men should be between 70 and 75 per minute.


Arrhythmias can occur in people who do not have any health problems in their heart, as is usually seen in people with heart disease. For this reason, it is first examined what the rhythm disorder is, and then whether there is any structural heart disease that causes this rhythm disorder on the ground.

Because arrhythmias can sometimes occur as a result of other systemic diseases other than cardiac (such as anemia, under or overwork of the thyroid gland, some hormonal diseases, some connective tissue diseases).


Some of the patients with rhythm disorders are unaware of these problems. In these people, arrhythmia is detected during a routine examination or during electrocardiography for another purpose. However, most of the patients;

  • Palpitation,
  • Irregular heartbeat,
  • The feeling that your heart will stop
  • Feeling of bird fluttering in your chest,
  • Feeling of emptiness, dizziness,
  • They apply with complaints such as shortness of breath.

Complaints such as dizziness, fainting or exertional dyspnea and dizziness can be seen in rhythm disorders that cause the heart rate to slow down.

Complaints such as dizziness and fainting can be seen, especially if there is a pause in the heart rhythm and these pauses are 3 seconds or more during active hours. However, a pause of 3 seconds or more during sleep is not always considered abnormal.

In cases where the heart rate is too high, complaints such as fainting and dizziness may occur. Especially if there are accompanying complaints such as fainting, dizziness or chest pain with a feeling of palpitations, this indicates the severity of the situation.

Tachycardia Treatment Methods

Tachycardia usually does not cause any serious consequences, but rarely can cause risks such as heart failure, stroke, and sudden death. Drugs, electrical methods or surgery are used in the treatment of tachycardia.

Medications: With medications, you can slow the heart beating too fast or return the rhythm to normal completely. These medications are called antiarrhythmics. There are various rhythm regulating drugs.

Electrical Treatments: In patients where drugs are ineffective or have side effects, rhythm disorders can be treated with a method called “catheter ablation”.

This procedure is performed in hospital by arrhythmia specialist cardiologists called electrophysiologists. Again, using a catheter, the piece of tissue that causes the heart to generate electricity can be detected and the arrhythmia focus can be burned or frozen.

Surgical Treatment: Some rhythm disorders can also be treated surgically, especially those who will be operated for another reason (eg bypass, valve surgery), rhythm disorder surgery can also be applied during the operation.
