Sinus rhythm
Sinus rhythm is a normal, healthy heartbeat. The heart beats in a steady and regular pattern, with electrical signals starting from the heart’s natural pacemaker (the sinus node). This means the heart is working as it should.
Sinus bradycardia
Sinus bradycardia means the heart is beating slower than normal but still in a regular pattern. It can be normal in healthy people, especially athletes or during sleep. In some cases, it may cause dizziness or tiredness if the heart is too slow.
Sinus tachycardia
Sinus tachycardia means the heart is beating faster than normal while staying in a regular rhythm. This often happens during exercise, stress, fever, or anxiety. It is usually a normal response to the body needing more oxygen.
Sinus arrhythmia
Sinus arrhythmia is a normal variation in heart rate that happens with breathing.
The heart beats slightly faster when breathing in and slower when breathing out. It is common in children and young adults and is usually harmless. A medical check is recommended if it comes with: Dizziness, Fainting, Chest pain or Shortness of breath.
Atrial fibrillation
Atrial fibrillation (AFib) is an irregular and often rapid heartbeat. The heart’s upper chambers beat out of sync with the lower chambers, which can reduce blood flow. AFib may increase the risk of stroke and usually needs medical evaluation.
Atrial flutter
Atrial flutter is a fast but regular heart rhythm caused by rapid electrical signals in the upper chambers of the heart. The heart beats faster than normal and may cause palpitations, tiredness, or shortness of breath. Medical evaluation is usually needed.
Multifocal atrial tachycardia
Multifocal Atrial Tachycardia (MAT)
Multifocal atrial tachycardia is a fast and irregular heartbeat caused by multiple areas in the upper heart chambers sending signals at the same time.
It is often seen in people with lung or heart conditions and usually requires medical attention.
Supraventricular tachycardia
Supraventricular tachycardia is a sudden episode of a very fast heartbeat that starts above the heart’s lower chambers.
It often begins and ends abruptly and can cause palpitations, dizziness, or chest discomfort.
Junctional rhythm
Junctional rhythm occurs when the heart’s natural pacemaker is not controlling the heartbeat, and another area takes over.
The heart rate is usually slower than normal and may cause fatigue or lightheadedness.
AV block mobitz I
Mobitz I AV block (Wenckebach) is a type of electrical delay where the heartbeat occasionally skips after gradually slowing. It is often harmless and may occur during sleep or in healthy individuals. In older adults (over 45), it’s not always harmless; it can progress to more severe block and cause symptoms like dizziness or fainting.
AV block mobitz II
Mobitz II AV block is a more serious condition where some heartbeats are suddenly blocked without warning.
It can cause dizziness or fainting and usually requires prompt medical care.
AV block first degree
First-degree AV block is a mild delay in the electrical signal traveling from the upper to the lower chambers of the heart.
The heartbeat remains regular and this condition is often harmless and symptom-free.
Frequent ectopy
Frequent ectopy refers to extra or early heartbeats that interrupt the normal rhythm. Many people feel these as “skipped” or “fluttering” beats. They are often harmless but may need evaluation if frequent or symptomatic.
Ventricular tachycardia
Ventricular tachycardia is a fast heartbeat that starts in the heart’s lower chambers. It can be dangerous because it may reduce blood flow and can lead to loss of consciousness or cardiac arrest. Immediate medical care is required.
