Regarding pulse rate
If only one day pulse rate stays between 150-200 bpm sinus tachycardia for seven hours only one day does it cause tachycardia induce cardiomyopathy or weaken the heart

Hi dear,
Transient tachycardia does not cause cardiomyopathy.
But if you are having rate between 150-200,it will be better go for ECG,TFT, serum electrolytes .
If you have history of chest pain,dizziness,sweating, family history of cardiac disease, family history of sudden cardiac death,then go for 24hr holter monitoring,2decho.

A single episode of sinus tachycardia (even 150–200 bpm) lasting several hours does NOT cause cardiomyopathy or permanent heart damage.
Tachycardia-induced cardiomyopathy happens only when the heart rate stays persistently high for weeks to months, not from one isolated event.
Common temporary causes include stress, anxiety, dehydration, fever, caffeine, thyroid issues, or supraventricular tachycardia.
Health Tips
Seek evaluation if: • episodes recur
• last long or occur at rest
• chest pain, dizziness, breathlessness, or fainting occur
If concerned, an ECG, thyroid test, and Holter monitoring can provide reassurance.

One single episode for a few hours usually does not weaken the heart. Heart weakness happens with persistent high pulse over many days or weeks.
Still, this needs proper evaluation — please consult me so I can guide you correctly.

A single episode of sinus tachycardia (150–200 bpm) lasting about 7 hours on one day is very unlikely to cause tachycardia-induced cardiomyopathy in a structurally normal heart.
Tachycardia-induced cardiomyopathy typically develops when:
• Heart rate remains persistently elevated (>100–110 bpm)
• For weeks to months continuously
• Or in recurrent, untreated arrhythmias
The heart can physiologically tolerate temporary high rates (for example during intense exercise).
Cardiac weakening happens from chronic sustained overload, not from one isolated episode.
However, a sustained resting sinus rate of 150–200 bpm for 7 hours is not normal and the cause must be identified.
Next Steps
Even though permanent damage from one day is unlikely, evaluation is important:
✔ Get an ECG
✔ Do a 24-hour Holter monitor
✔ Check:
• Thyroid function
• Hemoglobin
• Electrolytes
• Blood pressure
✔ Consider an Echocardiogram if episodes recur
Also assess triggers:
• Fever
• Dehydration
• Anxiety/panic
• Stimulants (caffeine, nicotine)
• Infection
If this was at rest and not exercise-related, it deserves proper cardiac workup.
Seek urgent care if:
• Chest pain
• Breathlessness
• Fainting
• Irregular pulse
Health Tips
✔ Stay well hydrated
✔ Avoid caffeine and stimulants
✔ Maintain regular sleep
✔ Monitor resting heart rate daily
✔ Avoid self-diagnosing arrhythmia without rhythm documentation
Most importantly: if episodes repeat, early intervention prevents long-term cardiac stress.
Since a 7-hour tachycardia episode is significant even if it doesn’t cause cardiomyopathy, I strongly recommend booking an online consultation so we can review your exact heart rhythm data and rule out underlying arrhythmia before it becomes a recurrent issue.

I 50-200 pulse is not normal .
Pulse should be less than 80/min ,but if it ws that much at any time it could be any cardiac abnormality my advise - physical /video consultation
Next Steps
Otherwise - 2Decho ,holter monitoring ,lipid profile ,kft
Health Tips
We can manage next episode n diagnose the exact cause why it hapnd.

Dear Patient,
A single episode of sinus tachycardia with heart rate between 150 to 200 beats per minute lasting for several hours usually does not cause tachycardia induced cardiomyopathy or permanent heart weakness in a healthy person. Tachycardia related cardiomyopathy typically develops when very fast heart rates persist repeatedly over days to weeks or occur frequently without control.
Common temporary causes include anxiety dehydration fever infection excessive caffeine lack of sleep or hormonal imbalance. Once the heart rate returns to normal the heart function generally remains normal.
What you should do
Ensure adequate hydration and rest
Avoid stimulants like caffeine energy drinks and smoking
Maintain good sleep and stress control
Monitor pulse and blood pressure
Tests to consider if episode was unexplained
ECG
Thyroid function test
Hemoglobin level
Electrolytes
Holter monitoring if recurrent episodes occur
consult me if
Chest pain breathlessness dizziness fainting or recurrent fast heart rate episodes
Resting heart rate persistently above 100
A single isolated episode rarely causes heart damage but evaluation is important if symptoms repeat.
For further guidance and personalized treatment you may consult me online anytime.

Only 1 day tachycardia cardia happened mostly due to non cardiac causes. But it's safe to rule out all cardiac causes also.
Investigation
ECG (most important)
Try to Repeat ECG when heart beat reach 150 again immediately.
CBC, LFT, RFT, ELECTROLYTES, TFT
PFT if respiratory symptoms
Monitor BP, sp02 ,pulse regularly
Next Steps
consult with all reports and detailed history for further investigation and management.
