Is a delta wave in my ECG harmful?

Is a delta wave in my ECG harmful?

It depends.: Delta waves are present in patients with wolf-parkinson-white syndrome (wpw). This condition can be associated with rapid arrhytmias. In some patients it may be asymptomatic. Patients with serious rhythm disorders can be treated with ablation of the accessory electrical pathway which results in abolition of the arrhythmias. At experienced centers the success rate is very good. ...Read more

Electrocardiogram (Definition)

Electrocardiogram (ecg, ekg) is a print-out of the electrical forces detected by electrodes on the chest wall, as electricity travels through the heart with each heart beat. The electrodes are placed in different positions, and each position "sees" the electrical activity of the heart from its own vantage point. Abnormalities in signal detected at chest surface ...Read more

Pulse 135 on ecg with short pr interval, delta wave. Pulse ranges 52- 161. Periods of SOB, chest pressure and dizziness. Cause? Getting holter tomorrw

Mgt: The holter will help to determine whether an irregular heart beat is present. Other causes include pulmonary hypertension and metabolic diseases affecting the heart. ...Read more

Latest ecg had delta wave. Have been SOB and pressure in my chest/throat (esp lying down). No meds. Appt cardiologist soon. Advice? Reason for delta?

Latest ecg had delta wave. Have been SOB and pressure in my chest/throat (esp lying down). No meds. Appt cardiologist soon. Advice? Reason for delta?

Delta wave, if true,: Is considered a sign of early excitation of the ventricles from atrial electrical activity. Usual atria to ventricle passage of electrical activity=via the atrioventricular node. A tiny percentage of people have additional connections of atrial to ventricle muscle cells which can bypass the AV node, activate ventricle cells earlier & is reflected in EKG as a delta wave; called WPW syndrome. ...Read more

What does elevated t waves on ECG mean?

What does elevated t waves on ECG mean?

Please clarify quest: The ECG may show either "tall" or "peaked" t waves, or may show "elevated" st segments. The description of "elevated t waves" is incorrect. Elevated st segments can mean many things, but at age 37 without any symptoms, are probably benign. Peaked t waves can also reflect a variety of issues, or may be benign. Would need to see the patient and the ECG to know for sure. ...Read more

What is a t wave abnormality on an ecg?

What is a t wave abnormality on an ecg?

Ecg: T waves represent the repolarization of the ventricles. The morphology of the wave is fairly uniform so when its vector is in the wrong direction we consider the t wave abnormal. ...Read more

What can cause the p-waves to be missing on a 4 lead ecg?

What can cause the p-waves to be missing on a 4 lead ecg?

P waves: If p waves are not seen on the surface ecg, either they are not present or the vector direction of the forces doesn't produce an adequate size p wave to see in the leads available. ...Read more

On an ecg, what does a "persistent s-wave (v5-v6)" mean?

On an ecg, what does a "persistent s-wave (v5-v6)" mean?

Not much: On the ECG, the first downward deflection that follows the dominant upward deflection is called an "S" wave and is part of the depolarization complex (called a "QRS complex"). Classically, the S wave is tiny or absent in V5-6. When the S wave is deep, the term "clockwise rotation" is used. (your heart is rotated in your chest) It doesn't connote any pathology. Not to worry. ...Read more

Did an ECG and got high t waves, what are the causes for that?

Normal: It can be perfectly normal. The classic pathological cause is elevated potassium but this would generally only occur in renal failure or overdose of a supplement. In people with acute chest pain, the very earliest sign of a heart attack can be a brief and temporary "hyperacute" peaking of the t wave. For most, though, it's a normal finding. ...Read more

Did an ECG and got high t waves. What are the causes for that?

ECG: There are t waves and then t waves. They can be prominent and have little meaning, very high t waves are usually caused by elevated potassium. ...Read more

What does an elevated t wave mean on an ecg? What conditions could it be?

Many causes: Elevated t-waves can have a variety of causes. Heart conditions, such as poor blood flow through coronary arteries, can cause elevation. So can abnormalities of different chemistries in your body, for example, an elevated potasium level. Many of these things have many causes, so you need to work with your doctor to first find out what abnormality might be causing it, and then why you have that. ...Read more

Can you tell me if on an ecg, what does a persistent s-wave (v5-v6) and mean?

Ecg: Persistent S wave in the lateral precordium doesn't have any particular evil important, it is often a normal finding. Occasionally it can be seen with pathologic conditions but there are generally other associated findings. ...Read more

What do the U waves signify on ecg? Why is it abnormal for them to be prominent?

Low potassium: Prominent u waves can indicate a number of things: low potassium. High calcium, long qt syndrome, drug exposure to digoxin, or an over active thyroid. Also can be normal in young patients. ...Read more

Can you tell me if on an ecg, what does a "persistent s-wave (v5-v6)" and mean?

Depends: A small S wave in these leads is usually normal. A prominent S-wave may be seen in patients with right sided overload conditions, such as pulmonary disease. A large S wave in V1 and lead I when the QRS is wide is seen in right bundle branch block (RBBB). In rare cases, a person with dextrocardia may be diagnosed by ECG with one feature being a persistent s-wave in V5-V6. Review with your doctor. ...Read more

My ECG showed repolirisation abnormalities in lead v5 and v6 the t wave was more flat or something is this bad? I'm 23.

Non-specific: What you're describing is rather non-specific, that is, you'd have to combine the EKG findings with a thorough history and physical examination by your primary physician. They may want to, then, refer you to a cardiologist or cardiac electrophysiologist to see if the findings are significant. Call 911 if you pass out, have chest pain, severe dizziness, or sudden onset shortness of breath. ...Read more

What are all the possible causes for a pointed P wave on an ECG?

Depends: But if truly a P wave, it depends on how pointy, as in height. P waves with an amplitude greater than 2.5 small boxes in lead 2 or 1.5 boxes in lead V1 suggest right atrial enlargement. If you've had an echocardiogram (sound study of the heart) like is mentioned in your "Procedures" then this would be more visible on this study. It may not mean anything. ...Read more

Are there any arrhythmias associated with pointed P waves on an ecg?

Pointed P waves: P wave is made up of the depolarization of the Right and Left atrium---on and EKG the first! /# of the wave is the RT atrium-----the last 1/3 is the LT atrium and the middle 1/3 is the summation of the RT + Lt if the P wave is notched it usually is Lt atrial enlargement if it is just peaked then it is usually Rt atrial enlargement---enlarging of the atrium especially the Lt can lead to a-fib ...Read more

Doesn't dangerously low potassium present itself as flattened T-Waves on ECG?

Doesn't dangerously low potassium present itself as flattened T-Waves on ECG?

Yes: But flat T waves are very non-specific. Flat T waves may have many causes. "U" waves are another clue but could be seen with other conditions such as bradycardia. A T wave change (and U wave) is an ekg clue which must be verified by serum potassium level. ...Read more

Is a small Q wave on an ECG significant?

Is a small Q wave on an ECG significant?

Probably not: By definition, a "significant" Q wave must be > than 40 msec in duration or > than 25-33% (depends on the reference) of the R wave height. Even by that criteria, many electrocardigraphically significant Q waves are seen in people with normal cardiac echo's and mri's. ...Read more

What is the indication for having a flat t wave in 12 lead ecg?

T Wave flattening: In the absence of clinical history or symptoms, t wave abnormalities such as flattened t waves are nonspecific. They may be seen in healthy individuals, leading to mistaken diagnosis of heart disease. Pathological causes are many & include myocardial ischemia, electrolyte abnormality, stroke, anticancer medications, and even with fever and after eating. Your dr, will tell you more. ...Read more
