An EKG displays P Waves, T Waves, and the QRS Complex. These may have abnormalities in people with A-fib. A "normal". EKG is one that shows what is known as sinus rhythm. Sinus rhythm may look like a lot of little bumps, but each relays an important action in the heart.
What are the early signs and symptoms of AFIB?
Those who do have atrial fibrillation symptoms may have signs and symptoms such as:
- Sensations of a fast, fluttering or pounding heartbeat (palpitations)
- Chest pain
- Dizziness
- Fatigue
- Lightheadedness
- Reduced ability to exercise
- Shortness of breath
- Weakness

What is the life expectancy of someone with atrial fibrillation?
It can lead to risks such as:
- An abnormal heart rhythm. On its own, this may not be life-threatening. But it can cause serious complications if untreated.
- Blood clots. When your heart doesn't beat strongly enough, your blood slows down and pools. ...
- Heart failure. Over time, your heart can get so weak that it can't pump out enough blood to meet your body's needs. ...
Does AFib show up on EKG?
Does AFib Show Up on an Electrocardiogram (EKG)? Yes. This simple, painless test is the most helpful to diagnose AFib. It records your heart's electrical activity.
What does AFib look like on a strip?

Something different in between your T waves and your PQRSMoreRight here you probably already noticed. Something different in between your T waves and your PQRS is you have what's called sawtooth appearance of an F wave.
How can you tell the difference between atrial ventricular fibrillation and ECG?
In AFib, abnormal p waves precede the QRS signal on the ECG. In VFib, there is a rapid irregular tracing but p waves and the QRS signal are unidentifiable. In most ECGs, AFib results in a rapid irregular pulse (QRS signal), while VFib results in no pulse (no clear QRS signal) so the ECGs are quite different.
What does AFib look like on a heart monitor?
Fibrillatory waves: Some people with A-fib will have fibrillatory waves on their EKG. These waves are a sign of the atria pulsing out of time. Fibrillatory waves can look a lot like P waves, and this can make an A-fib rhythm look like sinus rhythm.
What does a flutter look like on an EKG?

So each ofMoreAnd you'll typically see what people often refer to as water waves or a sawtooth pattern. So each of these bumps you see here represent atrial depolarization occurring at mostly regular intervals.
Does AFib have T waves?
Inverted T wave was commonly observed in patients with AF. The presence of inverted T wave during AF rhythm was associated with subsequent cardiac events such as cardiac death, myocardial infarction or hospitalisation due to heart failure.
Can AFib have P waves?
The cardinal features of atrial fibrillation are an absence of coordinated depolarisation of the atria (absence of P waves on the ECG/EKG) and unpredictable depolarisation of the ventricles (no pattern to R wave occurrence on the ECG/EKG).
What are the 4 lethal heart rhythms?
You will need to be able to recognize the four lethal rhythms. Asystole, Ventricle Tachycardia (VT), Ventricle Fibrillation (VF), and Polymorphic Ventricle Tachycardia (Torsade de pointes).
How to check AFIB?
The way to confirm AFib is with an electrocardiogram (EKG). The machine detects and records the electrical activity of your heart, so your doctor can see problems with its rhythm. You can do it in the doctor's office, or you may need to wear a device that keeps track of your heart's activity for a longer time to catch an episode.
What does an EKG show?
If an EKG shows AFib, your doctor may want to learn more about your heart. An echocardiogram or ultrasound can show valve damage or signs of heart failure. A stress test can reveal how well your heart does when it's working hard. Your doctor may also want tests to look for conditions that could have triggered your AFib.
Why is AFIB dangerous?
This causes the lower chambers (the ventricles) to beat out of sync. AFib can be dangerous because it raises your risk of stroke and heart failure.
How long does AFIB last?
14 / 23. When you first develop AFib, it may come and go. Your irregular heart rhythm may last anywhere from a few seconds to a few weeks. If a thyroid problem, pneumonia, or other treatable illness is behind it, AFib usually goes away once that cause is better.
What happens if your heart isn't pumping?
When your heart isn't pumping like it should, the slow-moving blood can pool inside, which makes it easier for clots to form. If that happens, and a clot travels through the bloodstream to your brain and gets stuck, you could have a stroke. People with AFib are five times more likely to have one. Swipe to advance.
How to control heart rate?
Rhythm-control drugs help keep the pattern of your heartbeat steady. Rate-control medications keep your heart from beating too fast. Daily aspirin or drugs called anticoagulants or blood thinners can help prevent clots and lower some people's chances of having a stroke. Swipe to advance.
What is lone AFIB?
Lone AFib. 11 / 23. When it happens without an obvious trigger, it's called lone AFib. This is more common in people younger than 65. You'll need treatment if a rapid heartbeat causes troubling symptoms. Doctors may also recommend treating it to lower the chances of stroke for people already at risk. Swipe to advance.
Graphic: ECG of Heart in Normal Heart Rhythm and in Atrial Fibrillation
In the case of Atrial Fibrillation, the consistent P waves are replaced by fibrillatory waves, which vary in amplitude, shape, and timing (compare the two illustrations below).
How to Interpret an ECG Signal
An electrocardiogram, ECG (EKG), is a test used to measure the rate and regularity of heartbeats, as well as the size and position of the chambers, the presence of any damage to the heart, and the effects of drugs or devices used to regulate the heart.
What is an EKG?
An electrocardiogram, ECG (EKG), is a test used to measure the rate and regularity of heartbeats, as well as the size and position of the chambers, the presence of any damage to the heart, and the effects of drugs or devices used to regulate the heart. The ECG signal strip is a graphic tracing of the electrical activity of the heart. ...
What is the first wave of EKG?
The first upward pulse of the EKG signal, the P wave, is formed when the atria (the two upper chambers of the heart) contract to pump blood into the ventricles. In A-Fib you will see many “fibrillation” beats instead of one P wave. A characteristic sign of A-Fib is the absence of a P wave in the EKG signal. The next large upward spike segment, the ...
What is the output of an ECG recorder?
The output of an ECG recorder is a graph (or sometimes several graphs, representing each of the leads) with time represented on the x-axis and voltage represented on the y-axis. A dedicated ECG machine would usually print onto graph paper which has a background pattern of 1mm squares (often in red or green), with bold divisions every 5 mm in both vertical and horizontal directions.
