Dear Mr I,
One of my many common encounter.
26 yo female, no underlying medical illness came with palpitations for 2 weeks.
History: accompanied by shortness of breath, dizziness, lasting 15 to 30 minutes. Work has been very stressful for her lately.
Examination: heart, lungs, heart beat regular, blood pressure normal. Done ECG, normal as well.
In this case, her palpitations is clearly associated with panic attack/ anxiety. In her case, self relaxation technique doesn't help. The frequency is so often that she needs to resign from work. Started her on oral medicine, symptoms much improved, but it takes time.
Palpitation is a subjective feeling of heart racing. If you feel that your heart racing is fast,and accompanied by evidence of fast heart rate like pulse oximeter or manual counting. This is what we called Tachycardia.
Sinus Tachycardia generally means a fast heart rate but it is regular in rhythm as the pacemaker in our heart is still functioning well. Generally, it is is less much of a concern as compared with non-simus tachycardia.
Frequently encountered causes in gp setting
-anxiety related
- acute illness especially with fever
- hyperthyroidism
-medication induced/ excessive coffee/ tea
-alcoholism
Less common cause
- heart related
-low red blood cell
- low blood sugar level
- endocrine causes
tips
- Take it seriously, if you have family history of hear disease/ premature death, or you symptoms is associated with syncope, chest pain
- You can't know whether it is sinus tachycardia or non sinus tachycardia until you do a ECG. So if you have palpitation, at least do a baseline ECG.
- in Gp setting, our main role is to differentiate cardiac Vs non cardiac cause of palpitation, and whether it is life threatening or not.
- when you come with palpitation, we will check your heart sound, pulse, signs of anaemia/ hyperthyroidism/ and your temperature/ review your medication.
- if we think it is heart related,
1) a structural heart condition like valves problem, we will refer you for a holter test, which is a small device to monitor your heart rhythm for 24 hours, as ECG done in our clinic can only show your heart rhythm at the point of testing only, and also Echocardiogram which is a ultrasound scan, a hand probe device, to visualise your heart more clearly.
2) ischaemic heart disease ( aka heart attack)
We will refer you for a exercise stress test to make your heart work harder, and monitor you for ischaemic changes.
Hope it answer your question. Thanks
