CLINICAL SIGNS OF ARRYTHMIAROHIT BACHWALA 512

Arrhythmias may not cause any signs or symptoms. In fact, your doctor might find you have an arrhythmia before you do, during a routine examination. Noticeable signs and symptoms don't necessarily mean you have a serious problem, however.

Noticeable arrhythmia symptoms may include:

A fluttering in your chest A racing heartbeat (tachycardia) A slow heartbeat (bradycardia) Chest pain Shortness of breath Lightheadedness or dizziness Sweating Fainting (syncope) or near fainting

Palpitations (rapid heartbeat or a pounding sensation in the chest) A "fluttering" or tremor-like feeling in the chest. Shortness of breath. Anxiety.

Tachycardia = Too fast A heart rate of more than 100 beats per minute

(BPM) in adults is called tachycardia. What's too fast for you may depend on your age and physical condition.

Slow HeartbeatSlow heartbeat (heart rate), called bradycardia, is an arrhythmia, or disorder of the heart’s rhythm. Each day, a normal heart beats about 100,000 times, at a rate any where from 60 to 100 times a minute. Changes in heart rate caused by activity, diet, medications, and age are normal and common. 

CHEST PAIN Chest pain. The first thing you may think

of is heart attack. Certainly chest pain is not something to ignore. But you should know that it has many possible causes.Chest pain may also be caused by problems in your lungs, esophagus, muscles, ribs, or nerves, for example. Some of these conditions are serious and life threatening

• . Depending on its cause, chest pain may be:

• Sharp• Dull• Burning• Aching• Stabbing• A tight, squeezing, or

crushing sensation

Blood and Oxygen(Shortness of Breath)• As the red blood cell moves

through the body, it delivers this bound oxygen to all of the body tissues.

• Normal heartbeats ensure that blood moves through the body smoothly so that the blood can efficiently deliver oxygen to the tissues.

• When the heartbeat is abnormal, blood moves through the body erratically, and oxygen cannot be delivered to the tissues correctly. This causes the tissues to become starved of oxygen and leads to shortness of breath.

DIZZINESS OR LIGHTHEADNESS

ECG CHANGES IN ARRHYTHMIA

Sinus arrhythmia:•Normal sinus P waves (upright in leads I and II) with a constant  morphology — albeit with an appearance suggestive of left atrial enlargement.•P-R interval is constant (no evidence of AV block).•The P-P interval varies widely from 1.04 seconds (heart rate ~57 bpm) down to 0.60 seconds (heart rate ~100 bpm); a variability of over 400ms

Diagnosis this ecg??

Ans:SINUS TACHYCARDIARhythm Regular

Rate Fast (> 100 bpm)

P Wave Normal, may merge with T wave at very fast rates

PR Interval Normal (0.12-0.20 sec)

QRS Normal (0.06-0.10 sec)

Notes QT interval shortens with increasing heart rate
